Bug description: C ompilation failure on preg_match_all()
Description:
------------
Hi there,
What we did? Update php 5.1.6 to 5.2.0.
What we wanted to happen? We expected the 5.2.0 version to behave/work as
the previous ones (5.1.2, 5.1.4 and 5.1.6).
What actualy happened? It didn't.
We have a php based app and we've been working since php version 5.1.2.
But with this new version (5.2.0) it seems to be a problem with the
preg_match_all() function.
Being the function call preg_match_all(string $pattern, string $subject,
array $coincidences), this are the values of the variables:
$pattern =
"/((field):(codigo_doa|titulo_obra|titulo_alternativo|num_serie|ejemplar_serie|ej
emplares_obra|nombre_tecnica|materiales_soporte|medidas_diametro|lista_artistas|m

45}))/";
$subject = "<table width="100%"> <tr> <td class="field_label">Tipo de

The function breaks down giving this message:
Warning: preg_match_all() [function.preg-match-all]: Compilation failed:
repeated subpattern is too long at offset 1153 in
/home/.../dcombs_controller.php on line 723
Warning: preg_match_all() [function.preg-match-all]: Compilation failed:

/home/.../dcombs_controller.php on line 723
We don't know if this is a bug, but we haven't seen any change related to
this on the 5.2.0 changelog. Just in case this could be a variable size
limitation (of 1024?), the $pattern is 1158 characters long and the
$subject is 1738 charachers.
Reproduce code:
---------------
See description.
Configure line: ./configure --prefix=/usr/local
--with-config-file-path=/usr/local/etc --with-apxs2=/usr/bin/apxs2
--with-mod_charset --with-openssl --with-kerberos --with-zlib
--enable-bcmath --with-bz2 --enable-calendar --with-curl
--with-curlwrappers --with-gd --with-ttf --enable-gd-native-ttf
--with-gettext --with-mcrypt --with-mysql --with-mysqli --with-snmp
--enable-wddx-with-xmlrpc --with-xsl --enable-sysvmsg --enable-sysvsem
--enable-sysvshm --with-freetype-dir --with-xml --with-libxml
--with-expat-dir --with-xmlrpc --enable-soap --enable-mbstring
--enable-mbstr-enc-trans --with-pgsql --with-tidy
Other configure options are removing --with-tidy.
Expected result:
----------------
The the preg_match_all() to work as it did on all 5.x php versions until
the date (except for 5.2.0).
Actual result:
--------------
Warning: preg_match_all() [function.preg-match-all]: Compilation failed:
repeated subpattern is too long at offset 1153 in
/home/.../dcombs_controller.php on line 723
