This is a *serious* HP-UX 9 problem of the zsh, which it didn't have
with previous versions (not with beta6 at least).
Situation :
$ sleep 10 (any process will do)
[Ctrl-Z]
zsh: 16763 suspended sleep 10
$ sleep 5 (any process)
*hang*
Fiddling with gdb shows that we are hanging in sigsuspend(), which is
called exactly once: signals.c with POSIX_SIGNALS defined.
Did someone change something there ?

This is a quite old problem (it is present at least since beta6). It is OS
dependent, and it is also present on ULTRIX. As I remember it appeared after
Richard rewrote the signals code. He promised to fix that.

I don't have any HP or DEC machines, so it is difficult for me to
track down. Does this still happen if you change POSIX_SIGNALS to
BSD_SIGNALS? It might be bugs in the Posix code for these machines.
If this fixes it, I can just force configure to use BSD signals on
these machines.

I can't reproduce this bug at all for Ultrix 4.3, even with
POSIX_SIGNALS.

I have been unable to reproduce this problem.

I build zsh (and all other autoconf-based software) with
CC="c89 -D_HPUX_SOURCE" configure
and below is the config.cache I have accumulated:
# This file is a shell script that caches the results of configure
# tests run on this system so they can be shared between configure
# scripts and configure runs. It is not useful on other systems.
# If it contains results you don't want to keep, you may remove or edit it.
#
# By default, configure uses ./config.cache as the cache file,
# creating it if it does not exist already. You can give configure
# the --cache-file=FILE option to use a different cache file; that is
# what configure does when it calls configure scripts in
# subdirectories, so they share the cache.
# Giving --cache-file=/dev/null disables caching, for debugging configure.
# config.status only pays attention to the cache file if you give it the
# --recheck option to rerun configure.

This bug seems to be compiler dependent. Here is a quotion from my BUGS file:
------------------------------------------------------------------------
On ULTRIX 4.2, if NOTIFY is unset, zsh gets SEGV each time a background
job terminates if compiled with gcc-2.6.3 or c89. It does not happen
with cc (non-ANSI compiler, ansi2knr is used). Terminal suspension
does not seem work regardless of the compiler. HP-UX seems to have
similar problems.
------------------------------------------------------------------------
And with gcc 2.6.3 on ultrix 4.2 ^Z does not work. The job won'n continue
after ^Z but the shell also hangs.
Bye,
Zoltan
