so pcre's version is 8.32, matches with document:
http://php.net/manual/en/pcre.installation.php
5.5.0 / 5.4.14 / 5.3.24 8.32
since your php is 5.3.29, so the bundled pcre version is 8.32
php 5.2.19 to 5.3.28, its version is 8.31
starting from php 5.5.10, the bundled version is 8.34.
suggestions of actions:
1.search php.net, maybe there is similar bug report already there
2.following the instructions in above document, build with pcre 8.34 by --with-pcre-regex=DIR
3.what's your current lsapi version ? 6.6 or 6.7 ? you can switch to the other one to see if any difference.
