As you have hopefully found, the error in libstdc++.log is: /libstdc++-v3/testsuite/22_locale/time_get/get/wchar_t/5.cc:15: int main(): Assertion 'err == std::ios::eofbit' failed. FAIL: 22_locale/time_get/get/wchar_t/5.cc -std=gnu++17 execution test Maybe there's a newlib configure flag we need to enable? Or a newlib bug...
