We understand that it might be difficult to find the necessary logs or reproduce the issue locally. If you can't get what you need from our CI within minutes, let us know and we will be happy to help.
We track this report status in https://linaro.atlassian.net/browse/GNU-1370 , please let us know if you are looking at the problem and/or when you have a fix.
I'm not sure what the problem is here. It looks like the build uses --enable-clocale=gnu and so I would expect the test to PASS on this target, like it does on x86_64-pc-linux-gnu. Maybe it's a newlib vs glibc difference. Looking into it ...
Indeed, these flags are passed to GCC's configure.
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...
Thanks,
Christophe
