Hmm. Interesting, I recompiled in DEBUG mode (as opposed to RelWithDebInfo) and the code seems to crash in a different location (I get a window, which wasn't the case before).
I added an assert to check whether bmp->extra is not NULL (it was used but not tested), that doesn't seem to be the problem though.
