Starts on m-i on a merge from m-c, https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&fromchange=98756a36223c&filter-searchStr=0c9e9779cc87f7f5098f2c10a023788a83fdcccc&tochange=4c58dd262bbe so either it came from elsewhere or something from elsewhere didn't like what it met on m-i.

Oh, what fun, it moved chunks.

The stack trace ends in Ion, so seems like a js engine issue. Nick, is this something you can help with or maybe direct us to the right person? Its a top orange at the moment.

Not something I can help with, but I'll needinfo a few of the jit folks. Jit folks: this devtools test is frequently crashing in the jit and it is a top orange. Can anyone help out? Thanks!

Just saw that we are crashing at 0x2b2b2b4b which is suspiciously similar to 0x2b2b2b2b which is a swept nursery. Jonco suggests on irc that this may be a case of a missing post-barrier.

Bug 1238935 is also crashing on 0x2b2b2b2b; it may or may not be related.

(In reply to Nick Fitzgerald [:fitzgen] [⏰PST; UTC-8] from comment #6) > Bug 1238935 is also crashing on 0x2b2b2b2b; it may or may not be related. And also bug 1236316 (see bug 1236316 comment 13). It looks like there's a GC bug somewhere in devtools code :( I couldn't reproduce that one, will try the other ones soon.

(In reply to Jan de Mooij [:jandem] from comment #7) > And also bug 1236316 (see bug 1236316 comment 13). It looks like there's a > GC bug somewhere in devtools code :( Oh the other one is shell-only and Jon is already on it. Let's find out what's causing that one.

Probably a duplicate of bug 1236316. Let's keep this open for now and check later.
