I got this panic ~10sec after starting gwenview, which is a KDE
program.  The kernel/userland is 3.0_BETA from 2005-08-24, and the
machine is DS10, which is uniprocessor.  I got a coredump and have a
netbsd.gdb.  I guess the trace is useless---I think maybe gdb is still
broken on alpha, or else I'm using it wrong (should have done 'reboot
0x104' right off the bat, and give up on this old idea of syncing the
disks first?).  If there is likely to be anything interesting in the
core file and someone is interested in looking at it, just let me
know, and I'll be happy to post it somewhere.  Thanks!

warning: Hit beginning of text section without finding
warning: enclosing function for address 0x4
This warning occurs if you are debugging a function without any symbols
(for example, in a stripped executable).  In that case, you may wish to
---Type <return> to continue, or q <return> to quit---
increase the size of the search with the `set heuristic-fence-post' command.

Otherwise, you told GDB there was a function where there isn't one, or
(more likely) you have encountered a bug in GDB.
