Subject: [ruby-core:111133] [Ruby master Bug#19147] `TestFileExhaustive#test_expand_path_for_existent_username` and `TestDir#test_home` fails on i686

Issue #19147 has been updated by vo.x (Vit Ondruch).


Interestingly, testing with commit:git|0436f1e15a, there are now additional spec failures which appears to be the same issue:

~~~

Testing with commit:git|66e5200ba4 on Fedora Rawhide, I observe following error just on i686 (other platforms are passing just fine):

Previously testing with commit:git|4b1504ae0a, the tests were passing just fine.
