+ * Don't use strlen() to calculate the length of
+ * the pcrs substitutes. They don't have to be valid C
+ * strings and getting their length wrong can result in
+ * user-controlled memory corruption.
+ *
+ * Thanks to Felix Gröbert for reporting the problem
+ * and providing the fix [#1627140].

* Revision 1.14 2006/12/24 17:27:37 fabiankeil
* Increase pcrs error code offset to prevent overlaps
* with pcre versions newer than our own.
