[Gnu-arch-users] 'tla file-diffs' error in some circumstances

[David B Harris]

I do hope this is the correct list to send this to. :) If it isn't, I'd
much appreciate it if somebody could bounce it to the appropriate forum.
(I'm subscribed to the list, by the way, so please don't Cc: me on
replies.)

Anyhoo, I've run into something of a bug. I've verified it with
tla-1.1pre4.tar.gz compiled myself, tla-1.1pre5.tar.gz also compiled
myself, and with Andrew Suffield's tla_20030908-1_i386.deb from
http://people.debian.org/~asuffield/arch/

In all cases, I'm using an up-to-date (as of Wed, Sep 10, 04:14 UTC)
Debian Sid system.

Below is a terminal log showing the problem I have; for easy searching I
have added the tag "# The problem starts here" for when it gets
interesting. Also attached are strace logs from a successful run and
from a failed run. (After writing this, I realised the terminal log was
quite long, so I have also attached it as terminal-log.txt in case
somebody wishes to view it outside their MUA.)

~/temp/ is a mountpoint and has one directory unwritable by myself,
~/temp/lost+found/
