I used to work on a legacy piece of business software, written mostly in C. One recurring issue we noticed about GDB was that compiling a "debug" version of the binary to be able to GDB it often fixed whatever problem the program was having, such that we were no longer able to reproduce the issue. So it wasn't uncommon for me to have this conversation with my manager:
Me: Customer is having their program X hit a SEGFAULT when they run it.
Manager: Did you transfer over a GDB version to backtrace the core dump?
Me: Yep.
Manager: What did it say?
Me: Well, when I run the same series of steps through the GDB version, it doesn't segfault, so I have nothing to backtrace.
Manager: Huh...
Me: What would you like me to do?
Manager: Move the production binary aside, drop in the GDB version. Leave it there.
