Hello,
Yes, gdb is really able to debug your code !
What I do to debug Python modules is :
1 - launch python with gdb (you don't need debug information in your
python executable to do so ...):
$ gdb python
2 - launch python and load your module
(gdb) run
Starting program: /usr/bin/python
(no debugging symbols found)
[Thread debugging using libthread_db enabled]
[New Thread 16384 (LWP 1885)]

3 - Hit "Ctrl-C"
Program received signal SIGINT, Interrupt.

0x40039178 in read () from /lib/libpthread.so.0
(gdb)
4 - place your breakpoints and continue execution
(gdb) b my_module.cc:54
Breakpoint 1 at 0x804a205: file my_module.cc, line 54.
(gdb) cont
5 - Enter some Python commands and debug as you will do with any program
once your breakpoint is hit.
Hope that's help,
Pierre
