Very simple patch against D1's gcx.d which throws OutofMemory when allocating
during a GC run
D's current garbage collector is completely unprepared to handle an allocation
which is called by a finalizer. Such an allocation puts D's GC into an
inconsistent state, which ultimately leads to memory corruption.
The GC should either forbid allocating in destructors (by throwing an
exception), or properly support it (which may be non-trivial).
If the first solution is chosen, it should be noted that there are instances of
allocations in destructors in Phobos as well (such as std.zlib).
