The consistency was likely due to running inside the debugger.

I tried looking a little deeper into this today, looks like the 
GC is collecting live objects.
The reason it keeps crashing in virtual dispatches is because 
when the GC places the free block into a list, it stomps on the 
vtable pointer (this is my working theory.) I'll rebuild to get 
the line numbers within druntime to have more confidence that 
this is what is happening.
