I tried using resizablepmcarray's append() in cardinal and I got 'double fre or corruption' on program exit. I tried to fix it, but I'm not sure about GC issues. As far as I can tell, the attached shouldwork.patch (which adds GC_WRITE_BARRIER before the write) should fix the problem, but it doesn't change anything. The attached doeswork.patch actually does fix the issue, but has some obvious issues. As far as I can tell, shouldwork.patch is doing the same thing as calling VTABLE_set_pmc_keyed_int does, so I'm not sure why it doesn't work. I couldn't reproduce it with ResizablePMCArrays directly, though. I'll keep working to see if I can generate a small test case. Anyone have any ideas?
