Clicking on Start, with JIT enabled, crashes. Disable JIT, works fine. Was testing to see if JIT improved performance of this demo (interestingly, Webkit was flatlining at 32 ips so I was curious if that was the natural speed of the demo for that ROM, or Webkit). Since it has been crashing for a week or two, figured I'd better make a note of it. http://crash-stats.mozilla.com/report/index/30c9825c-8c16-11dd-bd57-001a4bd43e5c http://crash-stats.mozilla.com/report/index/2735e1fd-8c16-11dd-b43a-001cc45a2c28 A couple of the crashes.

Can you plaese retest with a build form today (and please add the used build in the bug report) 0 js3250.dll nanojit::LIns::isop js/src/nanojit/LIR.h:365 1 js3250.dll nanojit::LIns::isTramp js/src/nanojit/LIR.h:383 2 js3250.dll nanojit::LIns::deref js/src/nanojit/LIR.cpp:244 3 js3250.dll nanojit::LIns::oprnd2 js/src/nanojit/LIR.cpp:627 4 js3250.dll TraceRecorder::set js/src/jstracer.cpp:1498 5 js3250.dll TraceRecorder::record_JSOP_GETELEM js/src/jstracer.cpp:4650 6 js3250.dll js3250.dll@0x66f15 7 js3250.dll js_Invoke js/src/jsinterp.cpp:1324 8 js3250.dll js_fun_apply js/src/jsfun.cpp:1731 9 js3250.dll js_Interpret js/src/jsinterp.cpp:4977 10 js3250.dll js_Execute js/src/jsinterp.cpp:1550 11 js3250.dll JS_EvaluateUCScriptForPrincipals js/src/jsapi.cpp:5078 12 xul.dll nsJSContext::EvaluateString dom/src/base/nsJSEnvironment.cpp:1574 13 xul.dll xul.dll@0x2f2be0

David is working on a crash that looks related.

Right. Sorry. Should have been more explicit that I was testing with that day's trunk build. Re: Comment #3 - even if it doesn't warrant duping yet, mind referencing the bug? I of course would be interested to know when the patches are committed and such.

http://crash-stats.mozilla.com/report/index/5f9761d7-9557-11dd-9f7e-001cc45a2c28?p=1 The trace appears to have changed slightly, but the interesting thing I wanted to note was while retesting with latest nightly, the first time I tried firefox froze up with 100% of CPU and I killed it after a few minutes. This trace is from the 2nd attempt, which crashes as usual.

Just to confirm, with build: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b2pre) Gecko/20081020 Minefield/3.1b2pre it still crashes...

Looks the same as the SCUMM bug, the fix works for me on both as well.
