Crashes in release mode

[kodo-simio]

When in release mode OpenSimplex2S.cpp crashes at line 1257 with a memory access violation.

((LatticePoint4D *)v.data)[j] = *(latticePoints[((int *)lookup4DPregen[i].data)[j]]);

I don't have the time to hunt down what's going on, which is a shame because this is otherwise nicely written procedural code.

thanks for reporting. How can I reproduce this error? I'm planning to investigate it asap

No problem. I tried compiling OpenSimplex2S into 2 different x86 Win32 Visual Studio projects - it worked fine in debug but when in release mode crashed at the noted line. I remember it was dereferencing the memory at *(latticePoints[ ((int *)lookup4DPregen[i].data)[j] ]) that caused the access violation. Unless something very strange is wrong with my PC then just creating a Win32 Visual Studio project, setting it to x86 and release mode and initializing both a OpenSimplexEnv and OpenSimplexGradients object should be enough to recreate the bug. Can I also just note that neither of these objects (OpenSimplexEnv & OpenSimplexGradients) are POD and there are no functions in your API for freeing their allocated resources when finished with them.
