Resolution Note (fix version 6000.2.0a6):
Fixes a stack corruption on SweepTestAll when doing a sweep test on a higher number than 32 colliders in a scene. Also replaced any allocators which use alloca to avoid any potential null expection crashes on IOS. We now allocate the returned hit results in one instance, instead of in a block based manner, which caused us to jump back and forth between the abstraction layer and unity several times, which caused the stack corruption to occur.
