[UNFINISHED] email to zsh

I am not on the list, so please CC me with any replies.

I'm running zsh 4.2.5 (built from sources) and 4.2.3 (stock Apple install) on Mac OS X 10.4.1. the bug existed in 10.4 as well. this is a consistently-repeatable crash.

my current working directory: /Users/boredzo/Projects/@otherpeoplesprojects/adium

I type:
    twe[tab: twedit] plug[tab: Plugins/]webk[tab: WebKit\ Message\ View/]aiwe[tab: AIWebKitMessageView]p[tab]

and it crashes (SIGSEGV). the full expansion, before the 'p', is:
    Plugins/WebKit Message View/AIWebKitMessageViewPlugin.m

there is no file 'Plugins/WebKit Message View/AIWebKitMessageViewPlugin.mp'; it was a typo. I recorded it for the sole reason that it's how to cause the crash. :)

this happened before I set up zshcompsys as well. my compctls:

compctl -g '*.z[12345678]' + frotz
compctl -g '*(/)' cd
compctl -k hosts telnet ftp ssh
compctl -g '*.py' + -f python
compctl -M '' 'm:{a-zA-Z}={A-Za-z}'
bindkey "^I" expand-or-complete-prefix
bindkey "^X^I" expand-or-complete

it still happens with zshcompsys. since setting that up, I have removed the cd, python, and case-insensitivity compctls, and it did not help.

with zshcompsys, this also makes zsh crash:

twe[tab] plug/webk/aiwe[tab]p[tab]

my setopt output:


with compctl, the crash log is:

with zshcompsys, the crash log is:

http://paste.lisp.org/display/9472 (this email would be over 20 K if I included it here.)

this is not a simple recursion-limit crash; it is worth pointing out that getfpfunc is called from all three of execif, execfor, and execwhile.

I have been unable to get debug symbols in zsh. I tried:

    CFLAGS=-g ./configure --with-curses-terminfo --enable-pcre --enable-zsh-secure-free
    (these being the same configure options I normally use)

but no source code references appeared in the crash log, nor debug symbols in the built executable.
