The crash is unimportant, as we force it due to the timeout. We ran out of memory which caused SimpleTest.js to fail to load, so that when the iframe got loaded and tried to run its own JS code, without its dependency (e.g. parent.SimpleTest) being set. 04:37:22 INFO - TEST-START | dom/canvas/test/webgl-conf/generated/test_conformance__glsl__implicit__multiply_int_mat2.vert.html 04:37:22 INFO - GECKO(756) | JavaScript error: , line 0: uncaught exception: out of memory 04:37:22 INFO - GECKO(756) | JavaScript error: http://mochi.test:8888/tests/dom/canvas/test/webgl-conf/mochi-single.html?checkout/conformance/glsl/implicit/multiply_int_mat2.vert.html, line 38: TypeError: parent.SimpleTest is undefined
