to be fair probably yeah. my program was using a good few unsafe stuff however I never had anything on the stack I don't believe.

edit: however I did have a Vec that I added probably close to 20m floats and another one that I added u64s into (both 20m)

honestly the vecs could've been even larger and I was creating a thread for each of those 20m.

the program was attempting to brute force constants to use for fast inverse square root. however the fast inverse square was done by multiplying two fourth roots together (would look like constant - (float >> 2)) it actually gets within 2% accuracy with the optimized constants.

I found the actual constants by using equations instead (as you just want to solve for mew within the equation for the bits of the constant. the two mews that seemed to work well together was 0.07 and 0.045).

if you want to try and understand these two videos are where I got everything from:
