Horrible code. First, it doesn't compile because there's no
;at the end of the class definition.And then more importantly you have a private destructor which means this CriminalScum's destructor will never be called, so you can't charge it with distruction either. Or are you telling me this CriminalScum has friends?
Also, if I'm not mistaken the uninitialized
propis not guaranteed to benullptrhere, so this private destructor could be trying to free from some random pointer.Yep, variables that are merely declared are not initialized, so their value is not guaranteed. Could be anything.
Correct me if I'm wrong, but I'm pretty sure some compiler settings can change this. I have a fuzzy memory of a bug that went away when compiled with debug flags enabled and the difference was that unassigned variables were being zeroed vs not zeroed.
Yes, actually at my job a co-worker just found exactly such a bug yesterday: Debug build zeroed out the variable and the release build didn't. So the bug only occurred in the release build, but could not be reproduced on the debug build where the developers work on. So in the end he found it because of the different compiler flags used for debug vs release builds at our work place.
