Comment #10 on issue 16675 by j...@chromium.org: Mac test regressions
20529:20532
http://code.google.com/p/chromium/issues/detail?id=16675
I managed to get some info for LayoutTests/fast/images/favicon-as-image.html
The problem happens for me about 1 in 50 launches of test shell.
(I was never able to repro with a 'refresh'.)
The last few messages before kaboom are:
[37208:2067:386400678971001:INFO:/Volumes/work/chrome/chromium/src/webkit/glue/plugins/plugin_li
st.cc(178)] Loaded plugin list in 227 ms.
Assertion failed: (!(ev->ev_flags & ~EVLIST_ALL)), function event_del, file
/Volumes/work/chrome/chromium/src/third_party/libevent/event.c, line 789.
Program received signal SIGABRT, Aborted.
Here's a stack which gets there:

The assert fired looks like a failsafe (make sure the flags are only values
we could possibly set for it). I can't
see how this could fire without it being a generic memory corruption
problem.
I don't really know if loading the plugin list (the immediately preceding
message) is relevant but it's worth a
shot, so cc'ing stuart / amanda to revisit this if we force-ignore
Quicktime in Mac for now (c.f.
