Is portsdb -U broken again?

[Roger Merritt]

Is 'portsdb -U' broken again, or is my machine getting ready to give up the 
ghost? For the last month or so, it seems that any time I try to do 
'portsdb -U' my machine runs about forty minutes to an hour, reports a 
couple of errors (telling me "" does not exist and the packing list is 
incomplete), and then reboots with "Signal 12, Page Fault in Kernel Mode 
(page not found)".

The same thing happens when I try to run 'make index', but I can run 
'portsdb -u' and 'pkgdb -F' ok.
