Reopening, as the above is not a valid grounds for closing this bug.

This bug refers to a crash in the official WebGL conformance suite, which we test the official WebGL implementation functionality against. Closing bugs on statistical basis loses valuable information for developers. Closing a bug as WORKSFORME means you have tried the bug on the target hardware and OS on the latest browser, and can verify that the steps no longer produce the bug. We should not close bugs on statistical grounds unless they were opened on statistical grounds in the first place, or if they don't have clear steps to repro. This bug has a clear STR attached to it. Edwin, could you please revisit and reopen any bugs you have closed which either refer to an official conformance suite and/or have a clear steps to repro?

Jukka, please retest this to see if it's still valid.

Retested this on the same hardware from comment 0 today on latest FF Nightly for Android, and the crash no longer occurs.

Thanks for testing this Jukka but since we don't know what fixed this I'm actually going to call it WORKSFORME.
