good catch dustin! I pushed to try: https://treeherder.mozilla.org/#/jobs?repo=try&revision=e3b2d88decd8a9ee1946d2345a82369a07fdaaa1 we still get leaks (although a different one) :( I am not sure who could look at this- since this is in /tests/dom/media/mediasource/test, maybe dminor can help me find the right place. here are the details I see in the log: [task 2016-09-20T15:52:43.983800Z] 15:52:43 INFO - ================================================================= [task 2016-09-20T15:52:43.983897Z] 15:52:43 INFO - ==1050==ERROR: LeakSanitizer: detected memory leaks [task 2016-09-20T15:52:43.983947Z] 15:52:43 INFO - Direct leak of 8 byte(s) in 1 object(s) allocated from: [task 2016-09-20T15:52:43.984015Z] 15:52:43 INFO - #0 0x4b247b in malloc /builds/slave/moz-toolchain/src/llvm/projects/compiler-rt/lib/asan/asan_malloc_linux.cc:52:3 [task 2016-09-20T15:52:43.986840Z] 15:52:43 INFO - #1 0x7fe7f6104778 (<unknown module>) [task 2016-09-20T15:52:43.987556Z] 15:52:43 INFO - ----------------------------------------------------- [task 2016-09-20T15:52:43.988439Z] 15:52:43 INFO - Suppressions used: [task 2016-09-20T15:52:43.988839Z] 15:52:43 INFO - count bytes template [task 2016-09-20T15:52:43.989258Z] 15:52:43 INFO - 127 1711 libc.so [task 2016-09-20T15:52:43.990171Z] 15:52:43 INFO - 834 26616 nsComponentManagerImpl [task 2016-09-20T15:52:43.990977Z] 15:52:43 INFO - 49 7056 mozJSComponentLoader::LoadModule [task 2016-09-20T15:52:43.992254Z] 15:52:43 INFO - 1 384 pixman_implementation_lookup_composite [task 2016-09-20T15:52:43.993536Z] 15:52:43 INFO - 178 7125 libfontconfig.so [task 2016-09-20T15:52:43.995075Z] 15:52:43 INFO - 1 32 libdl.so [task 2016-09-20T15:52:43.995713Z] 15:52:43 INFO - 17 4348 libglib-2.0.so [task 2016-09-20T15:52:43.996575Z] 15:52:43 INFO - 2 176 libpulse.so [task 2016-09-20T15:52:43.997721Z] 15:52:43 INFO - 1 28 libresolv.so [task 2016-09-20T15:52:43.998499Z] 15:52:43 INFO - ----------------------------------------------------- [task 2016-09-20T15:52:43.999547Z] 15:52:43 INFO - SUMMARY: AddressSanitizer: 8 byte(s) leaked in 1 allocation(s).

"leak at unknown stack" is pretty much as unactionable as it gets... Since I have an Ubuntu 16.04 system, I'm going to try a local ASAN build to see if any of these leaks reproduces.

Joel, it looks like the media leaks are now fixed: https://treeherder.mozilla.org/#/jobs?repo=try&revision=97e5846bab0c8b06cbcd110f695adf52fd90bc2a

dminor, can you just push that patch up for review? what you did looks correct.

It looks like there is now a failure in browser/components/search/test/browser_aboutSearchReset.js see: https://treeherder.mozilla.org/#/jobs?repo=try&revision=73a4fdb54a4a13a128ca1daecc7d641f3d9a03de

Is there anything left to do here?

we are 100% on linux64, no need for asan transforms!
