P1: Critical Description
Anaglyph rendering example crashes randomly at start when running the application in OSX or in Windows. Issue cannot be reproduced if ran under debugger.
Caught two different crash stacks from OSX, both basically indicate that the reallocated memory area is larger than there is available memory in the os -> the pointer to the reallocated struct is garbage:
