--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed. Note that with GCC 8 there's more verbose assert:
gcc pr85329.c -fsanitize=address && ./a.out
==6101==AddressSanitizer's allocator is terminating the process instead of
returning 0
==6101==If you don't like this behavior set allocator_may_return_null=1
