The crash was caused by allocating an uninitialized amount of memory. This fix initializes a bunch of variables that could cause the error. It should be possible to also fix this in the function that actually uses the uninitialized memory, but that could cause unknown consequences that are a bit too risky for 3.0. Just initializing some variables should be safe though. For more details see D13369. Differential Revision: https://developer.blender.org/D13369
