795215 - Mac slaves are prone to failing reftests with a pink pixel of death

Status: RESOLVED WONTFIX

(Testing :: Reftest, defect)

Description

We've had episodes of this before, but we've never bothered filing it to keep track of whether it's a single slave or not. Pretty sure it has always been OS X, though.

(so many failures we eventually die with an assertion, where the difference is a single pink pixel down at the very bottom of the image)

Recent PPoDers: talos-r4-lion-005, talos-r4-snow-014. Now that we know it's bad RAM, even though because our hardware diagnostics are inadequate to catch it and so we have to have the same broken slaves come back again and again, I'm inclined to just close this bug.

(To avoid this being closed as part of old intermittent-failure bug searches)
