>Description:
I am running FreeBSD-Current under vmware (on openSuse 10.3 (Quad Core 2)).  When vmware is configured to use two cores for FreeBSD csup (with socksify from net/dante) core dumps on signal 6 however if only one core is used then csup works fine.  Running cvsup with 2 cores does work without a problem.  

I'm running a stock GENERIC except all debugging options have been removed and with SHED_ULE enabled.  
>How-To-Repeat:
Run csup (and possibly with socksify) on SMP system with 2+ CPU's.
