The best way of finding core dumps with a Python extension is to compile
the extension source with '-g', and then follow these steps. You may want to
re-compile any other extensions you use (like Numeric) with -g.
% gdb /usr/bin/python2.1
(gdb) br _PyImport_LoadDynamicModule
(gdb) cont # repeat until your extension is loaded
(gdb) finish # to load your extension
(gdb) br wrap_myfunction # the entry point in your code
(gdb) disable 1 # don't want to break for more modules being loaded
(gdb) continue
