Well, I'll look into that in GDB somewhen, when I have time if nobody
else has any idea...
I tried four functions from three different areas of the kernel, and
all crashed, so I didn't bother to try more...  But I'll try more
somewhen and see if I find functions which don't cause a panic...

  Thanks,
