Comment= # 9 on bug 96678<= /a> from Nicolai H=C3=A4hnle 
Thanks.

The crash happens inside the implementation of std::stable_sort when called
from LLVM. An internal buffer pointer seems to be corrupted. Since the buff=
er
pointer lives on the stack I don't have a good explanation for this, just s=
ome
hypotheses we can follow up on:

1. Joost, does Awesomenauts do anything non-standard when linking to libstd=
c++?
Perhaps symbols get mixed up in a way that leads to the wrong code being
executed. It wouldn't be the first time that problems come from there, alth=
ough
usually when games do that they just fail to load in the dynamic linker.

2. Quentin, you could try running the game with Valgrind and see if anything
comes up. It's going to be slow, but if there is a stack-smashing bug here =
in
LLVM (extremely unlikely, but whatever) then Valgrind should catch it.
