Thank you for confirming this.

In fact you might be amused to know that when I do that, the allocation 
falls in the next bucket (twice as more bytes) due to the extra space 
required for tagging the chunk. This causes the crash to go away, since 
the offending array can still overwrite its bounds but not scrogg mallocs 
tables!
