How over-optimized is your build? Straight binary install or did you 
build it all with -O999 and suchlike?

fuse libs at the very least can be ruled out as a cause, since glfs 
3.0.x doesn't use them, it connects straight to /dev/fuse, AFAIK.

It's a little concerning that a process only communicating with kernel 
space through /dev/fuse can cause a reboot like that. One of the key 
points of fuse was to create enough separation to make that impossible...

Do you get a core dump? Is there a core.* file in the root directory ?
