I can reproduce 100% of time when executing nant.exe

Here is the backtrace:

My machine is a pentium4m with HT but I disabled ht. I will reenable it to see
if this still applies.

I'm using Ubuntu Hardy mono version. 1.2.6
mono --version
Mono JIT compiler version 1.2.6 (tarball)
Copyright (C) 2002-2007 Novell, Inc and Contributors. www.mono-project.com
        TLS:           __thread
        GC:            Included Boehm (with typed GC)
        SIGSEGV:       altstack
        Notifications: epoll
        Architecture:  x86
        Disabled:      none

Interestingly, if I just call gmcs which also creates a mono process, it
doesn't hang.

Thanks in advance.
