Summary: Running profiler crashed at libc.so!ifree because of SIGSEGV → Capturing profile crashed [@libc.so!ifree] because of SIGSEGV
It feels like a recent change in gecko tree is causing this bug. I am bisecting to find the guilty commit.
This is caused by Bug 1154115, more precisely commit https://hg.mozilla.org/mozilla-central/rev/ea1f7a05bd32. shu which is the original author of this patch seems to be in PTO. I am going to make further investigation later.

Possible dup of bug 1167230. wcosta, could you try out the patch in there?
Flags: needinfo?(wcosta)
The crash is over, but b2g profile still doesn't work due to the json file format change. I am going to close this bug as duplicate and file a follow up bug to update b2g profile to the new file format.
