I use Python with C (with SWIG), where the main module in Python processes data using C library. It crashes somewhere in the C library, so I want to analyse core dump and find the bug.

But, I do not have a regular executable to run with gdb, I have main.py, the library _library.so generated from my C code, and .o object files from C. How should feed gdb to see the core dump with this mixed code?

    IIRC you can do this by running python through gdb, i.e.

    gdb python
    gdb> run -m main.py
