So the problem is that one size calculation rounds up to multiples of a pointer size and the other doesn't; unfortunately the one that doesn't gets passed to malloc. The reason for the rounding up --a recent addition-- is that when you derive a subclass from tuple, string or long, the dict of the subclass instance (and its weakref list head) are allocated after the variable-length portion of the instance. I propose to fix the other size calculation to also round up. I'll leave it to you to fix this, since you've almost nailed this already (and since I'm not feeling so great right now).
