New issue 2843 by [email protected]: Flaky error on the 3.20 branch
http://code.google.com/p/v8/issues/detail?id=2843
I updated our d8 testing binary to the 3.20 branch and is seeing the
following flak.
Attached is the output of running dart2js on a dart test.
This is flaky passing/failing. On my z620 it is more or less failing on
every run, on the bots it is failing less.
It is actually not failing at the same location every time, but if I run
with --trace-opt i see this before it fails:
PASS: nongrowable-list-single!42 - length

PASS: nongrowable-list-single!42 - isNotEmpty
Around the failing part.
If I run with --always-opt I don't hit it (btw, it seems --noopt has no
effect anymore)
Marking this as high priority since it is on the 3.20 branch
