The gmp manual (https://gmplib.org/manual/Custom-Allocation.html) states > GMP may use allocated blocks to hold pointers to other allocated blocks. This will limit the assumptions a conservative garbage collection scheme can make. Thus we can't use ecl_alloc_atomic. We could just use ecl_alloc instead, however our implementation is already structured in such a way that it is sufficient to use ecl_alloc_uncollectable. The reason for that is that currently all bignums except those in the bignum registers in the thread local environment are allocated as compact objects so that we only need to call mpz_clear for the few non-compact objects in the bignum registers. See also commits 7b536161 and bd48b859. Fixes #485.
