crash in js::Put
Escaped String Impl
While trying to profile a performance issue with playing 4K videos on YouTube, all tabs would crash shortly after clicking Analyze in the Gecko Profiler. This crash happened about 75% of the time. I am using the latest 64-bit nightly on Windows 7. e10s is enabled. STR: 1) Install Gecko Profiler addon 2) Play a YouTube video at 4K using the HTML5 player (I was profiling ) 3) Profile during playback for at least 10-15 seconds 4) Click Analyze in the Gecko Profiler addon Actual results: All tabs crashed. Expected results: Profile should be loaded in cleopatra. bp-f7c38532-253f-47d8-b8d7-253842150326 bp-c56f0787-6257-457d-b855-3d3cc2150326 bp-911feb79-c66f-4fee-98b2-a8b992150326  https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Profiling_with_the_Built-in_Profiler  https://www.youtube.com/watch?v=s0MDY9fl-IA

[Tracking Requested - why for this release]: Crash since Nightly39 I think the following regression range is probably correct.

(In reply to Shu-yu Guo [:shu] from comment #5) > Alice or Trevor, could you confirm that the patch fixes the crash for you? Build from m-c tip 67f8d63b2cad : crashes Build from m-c tip 67f8d63b2cad + applied attachment 8584825 [details] [diff] [review] : no crash (attempted 5 times) So, the patch seems to fix the crash problem on Windows7.
Clearing ni? since Alice answered already. I'm not setup to build Firefox right now, but I'll be sure to test it out when it lands in nightly.
Backed out both https://hg.mozilla.org/integration/mozilla-inbound/rev/c68a6ebe6083 and https://hg.mozilla.org/integration/mozilla-inbound/rev/d1e9b787eaeb for causing, and then failing to fix, devtools-2 leaks.
This appears to be fixed. Thanks!
Status: RESOLVED → VERIFIED
Sounds like we don't need to track this, since it's fixed on 39, but please nominate it again if there's any problem.
