I managed to reproduce the issue building mingw-w64-crt, and the patch does fix that case too. (I could also verify that building the latest git master version of mingw-w64-crt isn't affected by the bug, as those versions explicitly specify unique --temp-prefix strings.)

I'll go ahead and send the patch for review then.
