pygame causes freevo to crash on amd64

Bug #138430 reported by Adapted.Cat on 2007-09-09
Affects Status Importance Assigned to Milestone
pygame (Ubuntu)

Bug Description

Binary package hint: python-pygame

There is a known stack overwrite problem in version 1.7.1 of pygame. If you look at the SVN repository under revision 1004 you'll see the fix, which involves using Py_ssize_t instead of int. Without this fix freevo is a non-starter on amd64 platforms.

So, it's a known problem, with a ready-made patch upstream - should be easy to fix.

Thanks for your work Luca; it is very good, it applies and builds correctly.
Have you also tested that:

1. It indeed solves the problem of having freevo not-working on amd64 machines.
2. The patch doesn't break any other package on a sample of the applications (apt-cache rdepends python-pygame) that depends on pygames?

I can't be definitely sure of this fix because I have no amd64 boxes to test it, but I'm confident because it has been applied upstream four months ago and no regressions have been discovered so far.

That patch worked for me. Freevo does not crash anymore on my amd64 machine.

Given that, I mark this bug as Confirmed.
