hi. i have a job that's been running in prod on an ubnutu box for a while. it's written in c++, compiled with gcc -O5. then it froze up. so i attached gdb and did a bt. can i use any of these hex numbers to cross reference back to my source code in some way? even if i need to re-compile it with a different paramter that ties either the assembly or the address space to source code? way back in the day on a now extinct platform we could compile code with the assembly and line offsets, then use the hex address of a running program to determine in exactly which source line a process was executing at that momement. can i do such a thing with my linux gcc app?
