 And could you copy-paste the crash backtrace to the PR audit trail,
 please?
 
 I thought this would be easy to reproduce by simply trying to run the
 ``gpt show'' command against any cd.  But within qemu it works just
 fine for me, for both a vnd0 and cd0 device.
 
 # gpt show /dev/cd0
 GPT not found, displaying data from MBR.
 
     start    size  index  contents
         0  106020         Unused
 # vnconfig -c vnd0 /boot-com.iso
 # gpt show vnd0
 GPT not found, displaying data from MBR.
 
     start    size  index  contents
         0  423936         Unused
