./mach reftest or ./mach crashtest fails with the latest build. Although, this same thing works with changes on August 10th or earlier. The error messages that I get are: npancholi-23547:mozilla-central npancholi$ ./mach reftests We're assuming the 'reftests' command is 'reftest' and we're executing it for you. REFTEST INFO | Checking for orphan ssltunnel processes... REFTEST INFO | Checking for orphan xpcshell processes... Error running mach: ['reftests'] The error occurred in code that was called by the mach command. This is either a bug in the called code itself or in the way that mach is calling it. You should consider filing a bug for this issue. If filing a bug, please include the full output of mach, including this error message.
