Please describe your issue in as much detail as possible:

I've identified 3 custom maps that seem to crash every time upon loading on both Linux and Mac clients, these crashes do not happen on Windows. The maps crashing are ze_shroomforest_p6, ze_shroomforest2_p6, and ze_frozentemple_rc1_1. I've confirmed this issue myself on Linux and Mac as well by talking to multiple other players who experience the exact same issue on Mac. The only difference between the shroom and frozentemple crashes is that shroom crashes during the loading screen while frozentemple crashes after picking a team. There seems to be rare instances where I can get into the maps (only verified on Linux), but only when changing from a previous map, never on a fresh load in. It should be noted that all three of these maps were ports from CS:S too.

To clarify any confusion, shroom 1 and 2 are different maps, the 2nd is just the same style and a continuation of the first.
