test
Product: gcc

I got
FAIL: 20_util/hash/int128.cc -std=c++17 execution test
with -mx32:
/export/gnu/import/git/sources/gcc/libstdc++-v3/testsuite/20_util/hash/int128.cc:12:
int main(): Assertion 'h(i) == i' failed.
#ifdef __SIZEOF_INT128__
std::hash<__int128> h;
__int128 i = (__int128)0x123456789;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
For x32, long is 32 bits. INT64 suffix should be used.
VERIFY( h(i) == i );
VERIFY( h(-i) == (std::size_t)-i );
VERIFY( h(~i) == (std::size_t)~i );
std::hash<unsigned __int128> hu;
unsigned __int128 u = i;
VERIFY( hu(u) == u );
VERIFY( hu(~u) == (std::size_t)~u );
#endif
