When compiling in debug mode with -O0 -g for ARMv7, and running the tests in debug mode we get lots of failures due to DoesGC issues. Example failure:


stress/typed-array-get-by-val-profiling.js.eager-jettison-no-cjit: Error: DoesGC failed @ D@131 CheckStructure in <eval>#A8MQjF:[0x723a81c0->0x745c2f68, LLIntEval, 1276]
