It's good to hear that your assertion failure was fixed,
but your fix sortof doesn't make sense. "osize" is the
correct thing to copy there, because the original memory
region presumably was only "osize" bytes long.
However, there may be some other code that calls gcRealloc()
with the wrong (i.e., too small) value for the "osize" parameter,
causing some data to not get copied.
