Answer 1

Do you really want a core, or just a stacktrace ? If all you want is a stacktrace you could take a look at the opensource here and try and integrate the code from there, or maybe just calling it from the command line is enough.

I believe some code in the gdb project might also be useful.

Another think you might want to do is to use gdb to attach to a running process.

$ gdb /path/to/exec 1234 # 1234 is the pid of the running process
