Summary: Glossary: Escaping forward slashes for PCRE functions
Product: MediaWiki extensions
Version: any
Platform: All
OS/Version: All

From
http://www.mediawiki.org/wiki/Extension:Glossary#Escaping_forward_slashes_for_PCRE_functions
On line 82 within the glossaryParseThisNode function, the following code
exists:
$texts = preg_split('/\b(' . preg_quote($term) . 's?)\b/iu',
$node->textContent, -1, PREG_SPLIT_DELIM_CAPTURE);
preg_quote() is meant to escape special regular expression characters from
glossary terms. However by default it will not escape the forward slash
character that has special meaning in PCRE regular expression functions. You
will therefore need to change line 82 to:
$texts = preg_split('/\b(' . preg_quote($term, '/') . 's?)\b/iu',
$node->textContent, -1, PREG_SPLIT_DELIM_CAPTURE);
Without this fix, glossary terms containing a forward slash may cause a lot of
rendering errors that make your MediaWiki installation unusable.
