Operating system: linux
PHP version: 5.2.6
PHP Bug Type: PCRE related
Bug description: _pcre_utt_names is overridden from libpcre.so and results in
\p match failure
Description:
------------
the pcre extension contains a copy of some specific version of libpcre,
with most of the names prefixed with php_ except for _pcre_utt_names which
is not prefixed. this means that if a libphp user such as apache2 also
happens to load libpcre (mine's directly linked against it so it loads
before libphp), the symbols from the latter may override _pcre_utt_names
and libphp will use the wrong names table when analyzing \p and \P (the
indices would come from php__pcre_utt which is specific for the
_pcre_utt_names table contained in the pcre extension).
Reproduce code:
---------------
preg_match_all("/\pL/u", "php", $matches);
print_r($matches);
Expected result:
----------------
Array
(
[0] => Array
(
[0] => p
[1] => h
[2] => p
)
)
Actual result:
--------------
Warning: preg_match_all() [function.preg-match-all]: Compilation failed:
unknown property name after \P or \p at offset 3 in <test.php> on line <x>
