Don't know how far we'll get without a testcase, but maybe bholley can spot something from the trace.

It is not that reliable - sometimes one have to wait for ~15 seconds until it crashes.

Confirmed this using today's daily m-c asan build ( https://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/choller@mozilla.com-2debc330caa1/try-linux64/ ).

This looks like another variant of bug 752340. With the assertion from that bug, this test case hits it immediately. With the assertion and the fix in place, it doesn't seem to crash, even after a minute or so.
