It seems I could solve the issue with the reserve() function, and 
it occurred twice so far.

I often have to disable bounds checking, since it takes up 
precious CPU cycles, instead I do it in an "at once" fashion 
rather than per-index access, and need to be done in such fashion 
with the graphics rendering functions I made.
