Unity crashes through access violation. (Probably related to GI)

    Hey there,

    I'm using version 5.2.1p4 and Unity occasional crashes through some access violation (this is, what Windows 7 tells me when debugging the crashed unity/build). It happens after I load a scene via Application.LoadLevel(). Baked GI is disabled. Precomputed Realtime GI is enabled. When I disable Precomputed Realtime GI the crash does not occur.

    Here is the callstack:

    Code (CSharp):
    1. >   mygame.exe!Enlighten::SolveDirectionalIrradiance<1>(class Enlighten::RadIrradianceTask const *,class Enlighten::RadiositySystem const *,class Enlighten::InputLightingBuffer const * *,union __m128 *,unsigned int &)   Unknown
    2.    mygame.exe!Enlighten::SolveDirectionalIrradiance(class Enlighten::RadIrradianceTask const *,class Enlighten::RadiositySystem const *,class Enlighten::InputLightingBuffer const * *,union __m128 *,unsigned int &)   Unknown
    3.    mygame.exe!Enlighten::SolveIrradianceTask(class Enlighten::RadIrradianceTask const *,void *,unsigned int &,unsigned int &)   Unknown
    4.    mygame.exe!Enlighten::MultithreadCpuWorkerCommon::DoSystemSolve(class Enlighten::CpuSystem *,int)   Unknown
    5.    mygame.exe!Enlighten::MultithreadCpuWorkerCommon::DoNextTask(int)   Unknown
    6.    mygame.exe!HLRTThreadGroup::ExitThreads(void)   Unknown
    7.    mygame.exe!Thread::RunThreadWrapper(void *)   Unknown
    8.    kernel32.dll!0000000076d15a4d()   Unknown
    9.    ntdll.dll!0000000076f4b831()   Unknown
    Does anyone see something suspious in there?

    We are experiencing the exact same issue with 5.2.1p4, slightly different callstack.

    Could you file a bug report with this information please. If you are able to find a way to recreate the issue reliably that would also be super helpful :D
