What good is crash instruction pointer?

[Robin Rowe]

Hi. I want my apps to keep a crash log that users can send in with bug
reports. I can use sigaction to catch the instruction pointer on SIGSEGV. My
question is can I do anything useful with that pointer address if a user
emails it to me?

Is there a map file I can generate that will tell me where in the source
code that pointer corresponds, what line of code the program choked on?

Thanks!
