The memory may have already been reallocated elsewhere!

Do not call C's realloc on GC allocated memory.

The best option is to avoid the GC whatsoever for memory that you want to  
manage that tightly.  Use c's malloc and free, which can be called from  
the dtor, no problem.  If the block has pointers to GC memory, remember to  
addRoot it (and removeRoot it in destructor).
