I can reproduce the issue with r258141 and r258024 using the command below.
run-webkit-tests --iterations 1000 --exit-after-n-failures 3 --debug --force-f fast/canvas/webgl/simulated-vertexAttrib0-invalid-indicies.html
[6/1000] fast/canvas/webgl/simulated-vertexAttrib0-invalid-indicies.html failed unexpectedly (test timed out, test was not run)
[7/1000] fast/canvas/webgl/simulated-vertexAttrib0-invalid-indicies.html failed unexpectedly (test timed out, test was not run)
[8/1000] fast/canvas/webgl/simulated-vertexAttrib0-invalid-indicies.html failed unexpectedly (test timed out, test was not run)
Exiting early after 3 failures. 3 tests run.
0 tests ran as expected, 3 didn't (997 didn't run):
Alexey Proskuryakov
Please revert r258025 (and unskip the test).
Kenneth Russell
@ap could we please hold off for a couple more hours? It looks like there is some old code in WebKit for vertex attribute 0 simulation that is causing this flaky crash, and that it should be #ifdef'd out with USE_ANGLE.
Dean Jackson
I've temporarily reverted 258025. I have a WIP fix for not-simulating vertex attribute 0. I'll turn them both on in the same patch.
Dean Jackson
"Fixed" in r258226
