   The only core file I could find was tstVMStructRC.core. The backtrace 
follows:

------

$ script gdb.log gdb 
./work/VirtualBox-3.1.8_OSE/out/freebsd.amd64/debug/bin/tstVMStructRC

   I've done another round of portupgrade(s) and tried rebuilding 
virtualbox-ose again to no vail.

$ uname -a
FreeBSD exxodus.fedaykin.here 8.1-PRERELEASE FreeBSD 8.1-PRERELEASE #6: 
Thu Jun  3 20:30:23 BRT 2010 
lioux at exxodus:/usr/obj/usr/src/sys/LIOUX  amd64

   On a side note, this might be a coincidence but I haven't been able 
to build virtualbox since the xorg update to 7.5 AND since my switch 
from 8-STABLE i386 TO amd64. Both happened around the same week. I have 
no idea which one is to blame.

   I did a clean amd64 install though, not an inplace upgrade.

   The latest build log can be found at:

http://people.freebsd.org/~lioux/virtualbox/2010060500/emulators__virtualbox-ose__build_log.txt.bz2

   The port work directory of the failed build can be found at:

http://people.freebsd.org/~lioux/virtualbox/2010060500/emulators__virtualbox-ose__work.tar.xz

   Let me know if there is anything I can try:

   Regards,
	Mario Ferreira
