Error accessing memory address 0x3b24481778: Input/output error." It's not related with SELinux, as I disabled selinux (SELINUX=permissive in /etc/selinux/config) and the problem persist. If you need any more info, please tell me.

This thread is closed.  Refresh page Posted by Greven Canada(835 posts)bio Date Thu 05 Feb 2004 10:36 PM (UTC) Message I'm trying to set a break point, but I'm getting this error: Quote:(gdb) break fight.c:525 Breakpoint 1 at 0x80e1bca: file fight.c, line 525. (gdb) cont Continuing. Warning: Cannot insert breakpoint 1. Error accessing memory address 0x80e1bca: Input/output error. The same program may be running in another process. I get similar problem when I try to boot it from within gdb,but the breakpoint is -2. My compilation flags are: Quote:DEBUG = -ggdb C_FLAGS = -g3 -g2 -W -Wall $(DEFINES) $(PROF) $(NOCRYPT) $(DBUGFLG) $(DEBUG) -export-dynamic I'm really unclear on what the problem may be, or what I can do about it.
