Status: RESOLVED INCOMPLETE

Description

[Geoff Brown [:gbrown]]

The webgl-conformance mochitests have not been running on Android for many weeks now -- bug 984523. When I try to run them now, there is a new crash, on Android 4.0 (panda) only.

More examples (they seem consistent to me):

Attachment: skip conformance/misc/uninitialized-test.html on Android

Unless a proper fix is immediately available, I would like to skip this test on Android so that we can start running the webgl-conformance tests on Android again.

I verified on Ash that skipping this test avoids the crash and allows the webgl-conformance tests to run to completion. https://tbpl.mozilla.org/?tree=Ash&rev=1e737fab7e9f
