a detailed description of the error. To define the condition symbol values (PARAMETER statements) in your program, include the following file: for_iosdef.for As fortran error codes described in the table, the severity of the message determines which of fortran iostat error codes the following occurs: with info and warning, program execution continues with error, the results may be incorrect with gfortran iostat severe, program execution stops (unless a recovery method is specified) In the last case, to prevent program termination, you must include either an appropriate I/O error-handling specifier and recompile

or, for certain errors, change the default action of a signal before you run the program again. In the following table, the first column lists error numbers returned to IOSTAT variables when an I/O error is detected. The first line of the second column provides the message as it is displayed (following forrtl:), including the severity level, message number, and ls dyna error part out of range the message text. The following lines of the second column contain the status condition symbol (such as FOR$IOS_INCRECTYP) and an explanation of the message. Number Severity Level, Number, and Message Text; Condition Symbol and Explanation 11 severe (1): Not a Fortran-specific error FOR$IOS_NOTFORSPE. An error in the user program or in the RTL was not an Intel Fortran-specific error and was not reportable through any other Intel Fortran run-time messages. 8 severe (8): Internal consistency check failure FOR$IOS_BUG_CHECK. Internal error. Please check that the program is correct. Recompile if an error existed in the program. If this error persists, submit a problem report. 9 severe (9): Permission to access file denied FOR$IOS_PERACCFIL. Check the permissions of the specified file and whether the network device is mapped and available. Make sure the correct file and device was being accessed. Change the protection, specific file, or process used before rerunning the program. 10 severe (10): Cannot overwrite existing file FOR$IOS_CANOVEEXI. Specified file xxx already exists when OPEN statement specified STATUS='NEW' (create new file) using I/O unit x.

Join them; it only takes a minute: Sign up Incorrect fortran errors: allocatable array is already allocated; DEALLOCATE points to an array that cannot be deallocated up vote error codes 0 down vote favorite I have written a fortran code which is failing in a way that I do not understand. I have tried to explain the scenario clearly below but please ask me to clarify if it is not clear. The code includes a subroutine SUBROUTINE TMGP(NSYM,NOB,NFT,DEN,ncod,PR,np,lden,NPMX,nuccen,mdel) IMPLICIT NONE ... INTEGER :: NINTS REAL(KIND=wp), ALLOCATABLE :: XBUF(:) ... print *,"xbuf allocated ?",allocated(xbuf) print *,"xbuf not allocated ?",.not.allocated(xbuf) if (allocated(xbuf)) then DEALLOCATE(xbuf) end fortran runtime error if if (.not.allocated(xbuf)) then allocate (xbuf(nints)) end if ... RETURN END SUBROUTINE TMGP However when I run this program it fails on the line: DEALLOCATE(xbuf) With the error forrtl: severe (173): A pointer passed to DEALLOCATE points to an array that cannot be deallocated With the output: xbuf allocated ? T xbuf not allocated ? F If I change the code to (and make NO other changes than adding this line): print *,"xbuf allocated ?",allocated(xbuf) print *,"xbuf not allocated ?",.not.allocated(xbuf) print *,"nints = ",nints if (allocated(xbuf)) then DEALLOCATE(xbuf) end if if (.not.allocated(xbuf)) then allocate (xbuf(nints)) end if and run this program it fails on the line: allocate (xbuf(nints)) and I get the message: forrtl: severe (151): allocatable array is already allocated With the output: xbuf allocated ? F xbuf not allocated ? T nints = 1 I am quite baffled by this as it seems to me the if statements I have used should make this kind of issue impossible and following the logic of the code these errors should not be possible. I am using ifort compiler, any ideas on what could be causing this issue or suggestions on how to fix it would be very much appreciated. Please let me know if any additional information would be useful. James fortran share|improve this question asked M
8.2, Handling Run-Time Errors Section 8.3, Signal Handling Section 8.4, Run-Time Error Messages 8.1 Compaq Fortran Run-Time Library Default Error Processing During execution, your program may encounter errors or exception conditions. These conditions can result from any of the following: Errors that occur during I/O operations Invalid input data Argument errors in calls to the mathematical library Arithmetic errors Other system-detected errors The Compaq Fortran Run-Time Library (RTL) generates appropriate messages and takes action to recover from errors whenever possible. A default action is defined for each error recognized by the Compaq Fortran RTL. The default actions described throughout this chapter occur unless overridden by explicit error-processing methods. The way in which the Compaq Fortran RTL actually processes errors depends upon the following factors: The severity of the error. For instance, the program usually continues executing when an error message with a severity level of warning or info (informational) is detected. For certain errors associated with I/O statements, whether or not an I/O error-handling specifier was specified. For certain errors, whether or not the default action of an associated signal was changed. For certain errors related to arithmetic operations (including floating-point exceptions), compilation options can determine whether the error is reported and the severity of the reported error. How arithmetic exception conditions are reported and handled depends on the cause of the exception and how the program was compiled. Unless the program was compiled to handle exceptions, the exception might not be reported until after the instruction that caused the exception condition. The following f90 command-line options are related to handling errors and exceptions: The -check bounds , -check overflow , and -check underflow options generate extra code to catch certain conditions. For example, the -check overfl
