           Summary: [WIN] Intermittent failure for jsc return value to
                    propagate through jsDriver.pl
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Windows 7
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: msaboff at apple.com


In JavaScriptCore/tests/mozilla/jsDriver.pl where an individual test is run and jsc is called, the exit code from running the test is sporadically 126 instead of 0 (success) or 3 (failure).

The relevant code in jsDriver.pl is:
        open (OUTPUT, $shell_command . $file_param . $path .
              $redirect_command . " |");
        @output = <OUTPUT>;
        close (OUTPUT);

After which $? should contain the exit code and/or terminating signal number.  The exit code is in bits 8-15.  Instead of getting the exit code from the jsc command, the exit code returned is 126.

Don't know if this is a windows or perl bug.

This has been coded around as part of the resolution to <https://bugs.webkit.org/show_bug.cgi?id=88118> with an appropriate FIXME in jsDriver.pl referencing this bug.
