Please excuse my delay in debugging this:

Hmm: then why could I unzip the same file before upgrading, but not
after?

OK, using the same path alleged to break above:

bash-2.05b$ pushd /d/temp

bash-2.05b$ mkdir -p qwer/asdf/zxcv

bash-2.05b$ mkdir -p

This works on my box, which is presently up-to-date. Are there other
hypotheses? If so, please let me know (and if possible, please reply
directly to me as well as to the list.)

If not: ISTM that something "down deep" in the base broke after 1.5.5-1:

0 both character-mode (e.g. unzip) and X (e.g. emacs) apps are broken

1 inputs that worked in 1.5.5-1 don't work now

2 failures are intermittent and apparently random

3 some error messages suggest malloc problems 

Am I missing something?
