vbnc is still crashing...

Repro:
wget
http://anonsvn.mono-project.com/viewcvs/*checkout*/trunk/mono-basic/class/lib/bootstrap/
cd bootstrap
mono vbnc.exe

Result:
(same crash as above, found here too:
http://mono.ximian.com/monobuild/builds/HEAD/sles-9-ppc/mono-basic/92409/logs/build.log)

I logged into the monobuild machine, and debugged a bit with gdb, here is the
output:

(gdb) run
