My OS seems to crash whenever there are two processes running, and I want to debug the problem. I know the address of the instruction that causes this problem, but I wonder how I could convert that address into a source filename and line number (perhaps by passing the -ggdb option to GCC and somehow extracting it from the ELF?)

Does anyone know if and how that's possible?

You may wish to use objdump -dSL that dumps the assembly, the source input line and the line number. A bit of grep magic will reduce the noise to what you are looking for.

Thank you, that helped
