strcmp core dumps

hi everyone, Right now when I do: strcmp(s1, s2); i get a core dump because at times s1 or s2 can be nothing so that makes strcmp() core dump. What is the solution, if at times I expect one of them (or both) to be NULL? I want to be able to compare that s1 is NULL and s2 is "blah" or...

Using GDB to analyse different CORE dumps

Hi, Can we modify the GDB source code so as to analyze core dumps from different targets? From my analysis, I think we need to build our section table statically for each target. i.e., including the various address boundaries in build_section_table() function. If this is the case, then the GDB...

AIX core dumps

My program is not dumping core when hitting a segmentation violation inside a thread. However, it dumps core when the segv occurs within main. Any ideas on how to diagnose this? AIX 5.3

core dumps

i had a situation where a process was defunct. preap would not reap the process and gcore would not work properly (not sure why). therefore, the suggestion was to force a panic and collect the core dump. obviously you could do a savecore -L and capture the dump without bringing down the system....

enabling core dumps for daemon processes

Stack only core dumps

ABRT-ACTION-GENERA(1)						    ABRT Manual 					     ABRT-ACTION-GENERA(1)

NAME

       abrt-action-generate-core-backtrace - Generates coredump-level backtrace

SYNOPSIS

       abrt-action-generate-core-backtrace [-v] [-r] [-d DIR]

DESCRIPTION

       This tool uses coredump from the file coredump and binary at the path stored in file executable in the problem directory to generate
       coredump-level backtrace.

       Coredump-level backtrace resembles ordinary backtrace in that it contains information about call frames present on the stack at the time of
       the crash. However, it only contains information that can be obtained from the coredump without debugging symbols available - mainly
       relative addresses of the stored instruction pointers. Such backtrace can still be useful for reporting and reproducing the bug and does
       not require debugging information files to be installed.

       The result is saved in the problem directory in a file named core_backtrace.

   Integration with libreport events
       abrt-action-generate-core-backtrace can be used as an analyzer for application crashes which dump core.

       Example usage in report_event.conf:

	   EVENT=analyze analyzer=CCpp
		   abrt-action-generate-core-backtrace

OPTIONS

       -d DIR
	   Path to problem directory.

       -r
	   Do not hash function fingerprints. Useful for debugging.

       -v
	   Be more verbose. Can be given multiple times.
