Hotspot and SS12 bug 6610361 ?

[David Holmes - Sun Microsystems]

I'd asked about this "locally" but now casting a wider net ...

In trying to build JRTS (based on JDK5) with SS12, on sparc we get 
bitten by bug 6610361:

Compiling 
/mnt/disk2/eng/dh198349/ws-bug6755041/ws/src/share/vm/interpreter/bytecodeTracer.cpp
cg: assertion failed in file ../src/ms_pipe/sp_softpipe.cc at line 3430
cg: Internal error: arc latency not covered
cg: 1 errors

To workaround this I had to drop the optimization level to O2 for over 
50 files in product and 60+ in fastdebug!

But I don't see any such workarounds in the JDK7 build files. I can't 
believe that we were that unlucky and we hit this bug 50+ times where 
Hotspot hits it zero.

This is the SS12 from /java/devtools  5.0 2007/05/03

Has anyone else encountered this building Hotspot?

Thanks,
David Holmes
