How to find location in code from address

[ChrisW67]

I have a program that I get a SEGV fault from.

Linux? Is the program writing a core file on crash? You could possibly use the core file. You may need to set the core file size ulimit greater than zero to get one, and it would probably help if the user was running a debug build
