Lua pcre inside nginx

NginX hooked pcre memory alloc/free functions pcre_malloc/free to use 
its memory pool, in order to work around its memory leaking problem. As 
a side effect, it reset this pool to NULL after every usage in core 
without considering possible external references. If you don't set pcre 
memory hooks to your own implementation, you will surely get the error.

ngx_lua has fixed this problem, and can use pcre related extensions 
normally after v0.1.6rc5.

* src/core/ngx_regex.c in NginX sources
* ngx_http_lua_patch.c in ngx_lua sources
