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!
