[Adonthell-devel] Bugs in automake 1.11.3 and Python 2.7.3

[Kai Sterker]

Ran into two issues today, that might affect others too.

The first one is that make install fails with automake 1.11.3, with
the following error:

  py-compile: Missing argument to --destdir.

It appears to be a known bug with fixes already submitted. There might
be even a newer version available, but not for my distro.
As a workaround, one can do

  sudo DESTDIR=/ make install


The second is a segfault within python itself (although it might be
the case that we somehow corrupt memory, as it cannot be triggered
reliably). To trigger it (about 1 time out of 10), just run worldtest
as usual and walk in southern direction. I believe it will either
happen immediately, before making the first step, or never at all. I'd
probably like to open a bug report, but before that want to make sure
that nothing we do causes this. So, does anyone have Python 2.7.3
installed and can reproduce the issue?

Btw., here's the stacktrace (gathered with the python-dbg package installed):
