Hmm. I can reproduce this on two of my systems: Slackware 14.1 and
Slackware 13.37. I can *not* reproduce it on Slackware 14.2 (which I've
only just got around to trying).

Slackware 14.1 (with multilib added):

Yes, I've confirmed that it does still happen with the current git code.

If you'd like a temporary shell account for testing purposes, send me
your SSH public key.

Thanks,
