Hi,

Below are 2 patches for the latest 5.2. The first patch rewrites
pcre_get_compiled_regex_ex() in ext/pcre/php_pcre.c from line 417, saving up
to 3 comparison statements (?:). The second patch removes a pointless
statement (setting a local variable right before a return statement) from
json_determine_array_type() in ext/json/json.c on line 92.

well about the pcre one I could argument that your patch makes the code bigger and potentially slower :P (due to cache misses) Anyway, I do trust the compiler to do such kind of trivial optimizations..
