HotSpot 2.0rc1-F (JDK 1.2.2) crashes while executing nsk/regression/b4189870.
In debug mode, the VM crashes with assertion failure "sanity check".
This is easy to reproduce on my machine: Pentium II, 1 CPU, 350 MHz, 128 M RAM.
Classic passes the test.
Similar bug was filed against Kestrel: #4293788 (but it is not the same)

Logs and test source follow:

$ java b4189870

#
# HotSpot Virtual Machine Error, EXCEPTION_ACCESS_VIOLATION
#
# Error ID: 4F533F57494E13120E43505002D9

Error ID = os_win32.cpp, 729

$ java_g b4189870

# assert(area == Thread::current()->handle_area(), "sanity check")
