As far as I know, the only known bug in RAII is 
https://issues.dlang.org/show_bug.cgi?id=14246 where constructors are not 
properly unwinding partially constructed objects.

My personal opinion is that constructors that throw are an execrable programming 
practice, and I've wanted to ban them. (Andrei, while sympathetic to the idea, 
felt that too many people relied on it.) I won't allow throwing constructors in 
dmd or any software I have authority over.

(Having throwing destructors is even worse, it's just madness. Although it is 
allowed in C++, it doesn't actually work.)

My personal opinion aside, it is a feature in D, and should work correctly, and 
is a serious issue for those that use throwing constructors. (It's not a 
disaster, though, as scope(failure) can be used to work around it.)
