By the way, this doesn't just block building Qt, but also using it for
development, because all uses of QVector that end up default-constructing an
element will run into this.

Note that this currently blocks building Qt with gcc 8. We could work around it
by turning our void* casts to char* casts, but we have a preference for fixing
this problem in the compiler.
