I think here we have a different case, the problem is that 2 pointers point to
the same memory location, one of the is local, the other returned by a
function. Now, since I can't parse C++, the question is if this is caused by
a compiler bug or by questionable uses of reinterpret_cast in the mozilla
sources.
