Trace from SIGSEGV crash

We get a SIGSEGV fault on jbossas start-up if -Xms/-Xmx are set bigger than about 128GB. It fails when set to 132000m.

This is jbossas-4.2.3-24.jpp5 / java-1.6.0-openjdk-1.6.0.0-1.22.1.9.8.el5_6 on RHEL 5.6

How reproducible:
Set -Xms132000m -Xmx132000m and start jbossas.

Steps to Reproduce:
1. Set heap size to 132000m (as described above)
2. Start jbossas
  
Actual results:
jbossas crashes with a SIGSEGV

Expected results:
jbossas starts normally

Additional info:
See attached trace.
