Thanks, will try 64-bit when possible.
No, there are no allocations in my code, I have set breakpoints
wherever I can throughout it and there are no allocations being
made every frame (its a video game). I don't use built-in dynamic
array directly, have my own wrapper for it.
My question is, are there any more places in druntime that I can
change so that I will get a notification when allocation occurs,
besides _d_allocmemory?
