>Description:
Sometimes the kernel panics when a new program is launched.  This is more frequent when using a graphical environment although does occur on occasion when using just a console.  

This panic started somewhere between FreeBSD 9.1 and 9.2 (while tracking stable/9).  Occurring at least at revision 24c4fd7 and d42e7f7 (using the git revision number from github.com/freebsd.  

I have 9 core dumps from this crash, six from the earlier revision (24c4fd7), one from the other revision (d42e7f7) and two from the current revision (05c3e78).  See http://people.freebsd.org/~dbn/crash/core.txt.7 for the latest crash log (additional logs available upon request).  
>How-To-Repeat:
Sporadic with no set procedure to trigger except using FreeBSD (triggers on program launch).  
>Fix:
