This usually happens because the allocation/free mismatches. (In cases such
as memory allocated by TCmalloc via the FastMalloc interface (fastMalloc,
fastNewMalloc) and tried to be freed by the system free.)
I support (1).
I think for (2), it would be better if the port maintainers would just try
to support the core (the new) allocator if it's possible. It would be
better to have only 1 allocator and optionally the system allocator for
