The regression test (testbase_nsk) nsk/regression/regresab66 crashes
the HotSpot Server VM (build 1.4beta-B36) in mixed mode on Solaris-Sparc.

The test generates a concurrently executed thread and expects
this thread to finish checking in loop a special flag,
but the HotSpot VM crashes.

This failure does not happen for the HotSpot Client VM and for
Ladybird 1.3.1-b3 Solaris-Sparc.
Also, the test passes in int and comp modes as well as on win32
in all modes.

This bug prevents the nsk/regression/b4322869 test from passing.
