core dump after system upgrade.

core dump after system upgrade.

[Le Wang]

Hi,

I've just upgraded my system to Mandrake 10.1, and I'm having a very serious
problem.  Zsh is core dumping when I navigate through completion choices with
menu completion.  At first I though it happened randomly, but I'm now able to
consistently replicate the problem.  I've tried the latest cvs code, and
almost every version going back to 4.0.9, and the problem persists.  I've
also trimmed my zshrc file to just 3 lines:

autoload -U compinit
compinit
zstyle ':completion:*' menu scroll=0 select=2

I compiled the cvs version with --enable-zsh-debug and get this from the core
file:

Core was generated by `zsh'.
Program terminated with signal 11, Segmentation fault.

What else can I try to fix the problem?

Thanks.

A bit more info:  I just realized that the problem is caused when any entry
on the screen is longer than the width of the screen.  If I make the terminal
size very large, the problem does not happen, however as I resize the
terminal window to be narrower, it core dumps as soon as any entry is split
over 2 lines.

In case its helpful, I ran this test on Solaris 9 with 4.0.6, 4.2.1
and 4.2.1-dev-1 and on FC3 Linux with version 4.2.0, but I can't
reproduce it.

I never had a problem before my system upgrade either.  I'm assuming it's
another package that got "upgraded" that's causing the problem.  I just don't
know which one.

No no no.  I went back and tried some previous versions again, and somehow
all versions prior to 4.2.0 work now.  So a bug would appear to have been
introduced in 4.2.0.

Here is a recipe:

$ xterm -geometry 40x10 -exec zsh -f

in the new window do the following:

  echo $ZSH_VERSION
  autoload -U compinit
  compinit
  zstyle ':completion:*' menu scroll=0 select=2
  rm -rf /tmp/zsh_test
  cd /tmp
  mkdir zsh_test
  cd zsh_test
  touch 'asdf asdf asdf adsf asdf adsf asdf asdf'
  touch b

now do:

  ls <tab>

hold on to tab for a FEW SECONDS to bring up menu completion, and it should
still work fine.

now, narrow the window until zsh segfaults.


Please tell me I'm not imagining this!
