New issue 1181 by [email protected]: Bug in OSR on ARM
http://code.google.com/p/v8/issues/detail?id=1181
It looks like there is a bug in OSR on ARM. Sorry I haven't had time yet to
look into details too much.
Raytrace sometimes fails when OSR is on. (Tested on a Tegra2)
I first spotted this bug a few days ago, probably when OSR was enabled by
default on ARM (r6784 on 15th Feb).
