Sure - I was reporting what I have so far.
 - cygwin x86_64 (LP64 model) is ok
 - mingw64 x86_64 (LLP64 model) fails
 - mingw64 i686 is ok

The problem is in mpz_popcount in the GMP library from MSYS2 x86_64,
which segfaults when calling mpn_popcount. I'll report back when I have
more time to investigate further.
