Useing more then 64 groups rules in soundmixers.txt silently corrups memory #1453
Description
This may be a known issue, but I think it's worth trying to describe it on GitHub.
When using more than 64 rules for groups in soundmixers.txt, the parser does not check that it goes beyond the boundaries and starts writing to global memory. As a result, we get that the sound subsystem memory is corrupted and the engine can crash on a random function.
How to reproduce:
Add more than 64 groups (the engine does not crash on some amount, but the memory is already corrupted). The engine will definitely crash on 72 - 100 groups.
As an addition, it would be nice to raise this limit so other mods on TF2 can use more than 64 groups (TF2 itself uses more).
