On NetBSD 8 and 9, in 64-bit mode, I see a test failure:
test-reallocarray fails with exit code 4.
The cause is that when n*s overflows, reallocarray(p,n,s) fails with
errno = EOVERFLOW — unlike other implementations that fail with errno = ENOMEM.
But EOVERFLOW is just as reasonable (even more reasonable, IMO) than ENOMEM
in this case. So, let's allow it, and make the test succeed without
overriding reallocarray().
