segfaults with cyrus-imapd 3.0.9 on latest arch linux

[Patrick Goetz]

Hi -

I can confirm this segmentation fault on my own Arch VM with cyrus 
installed from the AUR package.

As an experiment, I tried building the package with

    --disable-pcre

but then I can't even get the program to compile:

----------------------------
In file included from lib/glob.c:50:
lib/glob.h:57:5: error: unknown type name ‘regex_t’
      regex_t regex;
      ^~~~~~~
lib/glob.c: In function ‘glob_init’:
lib/glob.c:112:5: warning: implicit declaration of function ‘regcomp’; 
did you mean ‘memcmp’? [-Wimplicit-function-declaration]
      regcomp(&g->regex, buf_cstring(&buf), REG_EXTENDED);
      ^~~~~~~
      memcmp
lib/glob.c:112:43: error: ‘REG_EXTENDED’ undeclared (first use in this 
function)
      regcomp(&g->regex, buf_cstring(&buf), REG_EXTENDED);
                                         ^~~~~~~~~~~~
----------------------------

It would appear that --disable-pcre is a configuration option you can't 
actually use.
