You are most likely hitting cmd.exe at some point there. In cmd.exe, there
are some restrictions that are inherited by spawned processes AFAIU. For
example, the current directory cannot be a UNC path.

You are most likely running the interactive Cygwin session in MinTTY? Then
you do not get those restrictions. If you start Cygwin in a cmd.exe
window, you should see the exact same test failures again.

Ciao,
