Bus Error 10 Mac
takes a minute: Sign up I am getting bus error in following code up vote 3 down vote favorite 1 I am getting bus error in my code. With this code I am trying to convert numbers to words, but I know that there is a flaw in my logic. But before that, when I compile and run this code using compilation error c++ g++ in mac, I am trying to make this code run as it is and I am getting a bus error. Any help would be appreciated. When I run the code I get following output. I have debug messages to trace where the error occurs.

Code compiles fine but when I run it I get a 'bus error'. No more details are given by the program. I have narrowed it down to when I call fread.

Hello All, I'm not a C/C++ programmer, but I'm familiar with this programm language. The thing is that I'm trying to compile and run DDS (Darwin Streaming Server) on "Gentoo on Sparc" architecture. Although I've managed to compile DSS under my arch. bus error 10 I'm constatntly get "Bus error" while trying to connect to DSS with QT player. I've read that: "The "bus error" signal usually means a data access was not properly aligned. It is always due to an error in the program. One major cause is accessing data via a pointer of a different type that has different alignment requirements. Example: Code: short s[2]; // 2-byte alignment int* p = (int*)s; // pretend the 2 shorts are one int int i = *p; // bus error is likely On SPARC, an int must be aligned on a 4-byte boundary, but a short only needs 2-byte alignment. The attempted load fails with a bus error if array s was not 4-byte aligned. Here is the example of resolution for this kind of problem on another project (a snap from the .diff): Code: @@ -499,8 +499,11 @@ conn->request_len -= req->len; if (conn->request_len == 0) break; - +#if defined (__i386__) req = (void *) req + req->len; +#else +memmove(&conn->request, (void *)req + req->len, conn->request_len); +#endif } if (conn->request_len > 0 && req != &conn->request) So I thought Fatal Errors Logic Errors Note that the error messages shown below may be specific to our compiler/linker or machines. Nonetheless, other systems and compilers will provide similar information. Compiler Messages When the compiler is compiling your code (i.e., converting your code into instructions the machine understands), it will report problems that it finds in your code. Aside: Here, we are being technical and refer to compiling as the stage before linking. Linking is when all the compiled pieces of a program and the libraries it uses (e.g., for cin) are put together to form an executable. Often, compiling and linking together are just referred to as compiling. There are two severities of messages the compiler can give: Compiler Warnings A compiler warning indicates you've done something bad, but not something that will prevent the code from being compiled. You should fix whatever causes warnings since they often lead to other problems that will not be so easy to find. Example: Your code calls the pow() (raise to a power) library function, but you forgot to include math.h. Because you've supplied no prototype for the pow() function (its in math.h), the compiler warns you that it assumes pow() returns an int and that it assumes nothing about pow()'s parameters: somefile.cpp:6: warning: implicit declaration of function `int pow(...)' This is a problem since pow() actually returns a double. In addition, the compiler can't type-check (and possibly convert) values passed to pow() if it doesn't know how many and what type those parameters are supposed to be. Note: The compiler will label warnings with the word warning so that you can distinguish them from errors. Compiler Errors A compiler error indicates something that must be fixed before the code can be compiled. Example: You forget a semi-colon (;) at the end of a statement and the compiler reports: somefile.cpp:24: parse error before `something' Always remember to fix the first few errors or warnings, since they may be causing all the rest. Compiler messages usually list the file and line number where a problem occurs.
