perl -MFile::Temp -e'my ($fh, $path) = File::Temp::tempfile(); close $fh; local ($!); my $ok = chmod( 0111, $fh ); print "ok? [$ok] err? [$!/$^E]"'

The above breaks on every Perl version that I've tried: 5.14.4/Linux, 5.18.2/Mac, and 5.20.0/Mac.

If you take out the "local ($!);", then it populates $! as you'd expect.
