Memory (Debugging with GDB)
The addresses and contents printed by the x command are not saved in the value history because there is often too much of them and they would get in the way. Instead, GDB makes these values available for subsequent use in expressions as values of the convenience variables $_ and $__.

It just hangs like in an infinite loop. Any suggestions?

You don't know whether it's waiting for something or is actually in infinite loop.

Your first steps should be:

  1. Run top and see whether GDB process is consuming CPU or is increasing in memory and
  2. Run strace gdb to see which (if any) system calls it is performing.

With that info, further guesses could be made. It may also help to know which system you are on, and which version of GDB you have installed.

Update:

Running strace gdb results in a infinite loop outputting: readlink(“/usr/bin/python”, “python”, 4096) = 6

So you have /usr/bin/python which is a symlink to itself.

Yes, that would cause all kinds of problems (including not being able to actually run python from command line).

Remove that symlink (/usr/bin/python is supposed to point to python2 or python3).
