Bug #23776 --with-regex=apache makes apache unable to resolve 'php_regcomp' when starting.

Status: Not a bug Package: Dynamic loading

Private report: No CVE-ID: None

If I compile PHP as apache's module, using 'apache' regex, then Apache fails to start complaining: 
-- Cannot load /usr/apache/lib/libphp4.so into server: /usr/apache/lib/libphp4.so: undefined symbol: php_regcomp

The other 'configure' options does not affect this problem. Specifically, 'configure' may be:
./configure --prefix=/usr \
   --with-apxs=/usr/apache/apxs \
   --with-regex=apache \
   --disable-all --disable-cgi --disable-cli --disable-ipv6

My apache configuration seems relevant to this issue:

- apache-1.3.27, patched with 
- mod_ssl-2.4.18.

Apache compile-time 'configure' options include --disable-rule=WANTHSREGEX. This forces apache not to use bundled regex library, but use 'system' regex instead.

The same problem was also observed with prior 4.3.2RC3 PHP release candidate.

Yes, I know that workaround is to indicate '--with-regex=php', and use bundled regex library. But... what shared libraries exists for ?

Don't touch it.

Well, well...
Bogus answer, not question...
You should give me the catch to make me know about.
