Patch for regcomp.c

Hi,

currently, regcomp() misses a lot of checks for memory allocation
failures, and it also does not properly release memory on error paths.
This means a malloc error usually causes either a SEGV or a memory
leak.

The attached patch (regex.diff) adds the return value checks and
memory deallocation on failures.
