with mustang b27 64 bits jvm, vmark/vtest/atg/tomcat all crashed on
solaris sparc.
The crashes only happened on solaris sparc with 64 bits jvm.
It's a regression from b26.
The crashes happened within an hour.

For example,
Tomcat crashd on jtg-e450-3.sfbay
# uname -a
SunOS jtg-e450-3 5.10 Generic sun4u sparc SUNW,Ultra-4

# pwd
/bt/Tomcatrun.915.-d64
# tail run.tomcat.out
Unexpected Error

SIGSEGV (0xb) at pc=0xffffffff38018128, pid=2007, tid=43

Do you want to debug the problem?

To debug, run 'dbx - 2007'; then switch to thread 43
Enter 'yes' to launch dbx automatically (PATH must include dbx)
Otherwise, press RETURN to abort...
