GDB is the GNU Project Debugger.

I have some errors on compiling GDB:

• gdb configure error: no termcap library found.
  On searching, I find this solution to install ncurses-devel.
  I downloaded and extracted ncurses-devel-5.2-2.i386.rpm.html.
  Normally, you can install rpm by
  rpm -i –nodeps ncurses-devel-5.2-2.i386.rpm
  If this fails because it requires superuser access, you can extract with rpm2cpio using
  rpm2cpio ncurses-devel-5.2-2.i386.rpm > ncurses-devel-5.2-2.i386.cpio
  and then with cpio
  cpio -i < ncurses-devel-5.2-2.i386.cpio

• cc1: warnings being treated as errors
  See GDB Compiler Warnings.
  I reissue the failed command but removing -Werror from it to bypass the error.

See Debugging Extension Modules on Linux/Unix and Debugging Under Unix: gdb Tutorial.
You can debug python script as follows:

myhost> gdb
(gdb) file python
(gdb) run yourprogram.py yourargs
..
Program received signal SIGSEGV, Segmentation fault.
