Progress!
This shows that the crash happens during processing of slot 12.
(Looking back through the output of "amtape inventory" you sent, it
appears that this slot contains a tape with barcode 000029L7.)
An interesting thing to note is that the *label* variable for that slot is
uninitialized -- perhaps that's what is causing the crash?
To test that theory a bit, I've attached another patch to try.
Unfortunately this one is in a file used by the oldest.pm algorithm,
too, so you'll probably want to revert the file back to the original as
soon as you've finished teating, to make sure that the patched version
doesn't affect an actual amanda run.
So, basically save a copy of the original
/usr/local/share/perl/5.22.1/Amanda/ScanInventory.pm
file, then apply the patch attached to this email in-place to that file,
and run the
amcheck -s -otaperscan=taper_lexical daily
test again. (I don't expect this patch to prevent the crash, but
hopefully the new log messages will narrow down exactly where it is crashing.)
