Looks like this was fixed in patch 124861-04:

6610361 cg assertion in "arc latency not covered"
Not sure why this bug isn't visible on, doesn't seem to be a security bug.

Exactly what /java/devtools do you have, East coast?
I'm surprised we haven't seen this problem too.
I wonder if it depends on the specific Solaris 10 you are using.
What does 'uname -a' and 'CC -V' say?

(FYI: background for non Sun people, /java/devtools is a shared area where
       we place images of the Sun Studio compilers and other tools).
