Issues that only appear at higher optimisation levels also often involve 
undefined behaviour.

So here is what happened: SIGSEGV means the program tried to access 
memory that it should not have. The page was not mapped or had the wrong 
permissions for what it was trying to do. The memory address that it 
attempted to access is also shown.

And this is where it happened. Since this is not a full debug build, 
there is no line number information, but you at least know which method 
is doing the bad memory access.
