A program I am working on is crashing and generating core dumps. I think that the issue is related to the arguments that it's being called with, some of which are automatically generated by another (rather complicated) program. So I've tried using
gdb to debug, or
file core.MyApplication.1234 to get the arguments.
However, the command is pretty lengthy, and the output looks something like:
core.MyApplication.1234: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style, from './MyApplication -view -mwip localhost -mwnp 12345 -mwlp 12346 -mwti 12347 -Debu'
(I did change the names for this example, but you get the idea.)
I know for a fact that there were several more arguments after this, but in the core files the command is always truncated at 80 characters. Both
file report this. Looking at the output of
objdump I'm not sure the rest was even written into the core dump, because it appears to cut off after "-Debu" too.
I am running this on RHEL6. I found this thread from 2007 describing a solution for Solaris systems using
pargs, but that's not a valid command on my system, and the Red Hat "equivalents" I've found only work on running processes, not a core file.
How can I recover the entire command used to run the program? Is that even possible?
