Re: pcre module help

Hi all,
First, thanks for the documentation patch. Secondly, I am unable to use the pcre module on Mac OS 10.3.4. Regarding the bus error:

% zsh -f
% print $ZSH_VERSION
% zmodload zsh/pcre
% text=d
% [[ "$text" -pcre-match ^d+$ ]] && print text variable contains only "d's".
zsh: bus error  zsh -f

(at that point the shell exits)

I haven't used gdb before, so please correct me if this is wrong:
1. In one shell, I do the following:
% zsh -f
% zmodload zsh/pcre

2. In another shell, I did:
% ps ax|grep "[z]sh -f"

Please let me know if other/more information would help. Regarding the "pcre_compile: not available on this system" message:

% zsh -f
% zmodload zsh/pcre
% pcre_compile ^d+$
pcre_compile: not available on this system

I just attempted to compile zsh 4.2.0 with the --enable-pcre option again and noticed the following:

checking for pcre_compile... no
checking for pcre_study... no
checking for pcre_exec... no
checking pcre.h usability... no
checking pcre.h presence... no
checking for pcre.h... no
checking for library containing pcre_compile... no

What could it be? I'm happy to get you more information/test patches, etc.

The shell crashing is consistent when I try to use -pcre-match after
attempting to run pcre_compile.  Also, the -pcre-match method is not
mentioned in the zshmodules manual.
