It doesn't work here:
comtest.c:103: Test failed: Moving temporary file failed comtest: 1 failures in child process
I think it's trying to move the file in the temporary directory to itself.
It works on the testbot: https://testbot.winehq.org/JobDetails.pl?Key=43124 Moving a file to itself should generally work, too. Where is "here"? Can you tell me where it fails, so I can try to replicate and fix the issue?
