Hi people,
Season's greetings to you all.
Time for a report after 9 years away from zsh development...
It's nice to see that many people of that time are still around :-)
I've stumbled on what I consider a bug in 4.0.6: if I use this command
in /etc/zshenv
ulimit -HS -d 1048576 -v 1048576
I get "/etc/zsh/zshrc:-1: fatal error: out of memory" when I start the
executable. This doesn't happen with 4.0.4. I tried 4.0.6 with the
original distribution and with Debian's patches. The Debian binary,
which uses dynamic loading, also chokes. The problem goes away if I
remove the -v 1048576 portion of the line.
This is the config I used:
./configure --prefix=/usr --bindir=/bin --mandir=/usr/share/man --infodir=/usr/share/info --enable-maildir-support --enable-max-jobtable-size=256 --enable-function-subdirs --enable-site-fndir=/usr/local/share/zsh/site-functions --with-curses-terminfo --enable-etcdir=/etc/zsh --disable-dynamic
Independently of my .zshenv and other init files, I find it strange
that the program doesn't run because the memory limitation is not at
all stringent.
If there's something else useful to inform please tell me.

This is a bug in the C preprocessor #ifdefs in the code that interprets
the ulimit command. It's pretty tangled what with trying to compensate
for about three different possible implementations, and we haven't got
it straightened out yet. The effect of the bug is that the argument to
-v is interpreted as bytes rather than kbytes.
If you use the "limit" command instead of "ulimit" this bug does not
occur:
limit -hs datasize 1048576 vmemorysize 1048576
