Although previous post describes optimal solution,
note that 'pcre_max_stack_offsets'(ifUsed) must be defined in two places to work,
it won't work if you just define it in pcre package.

Default 30 value still doesn't work correctly,
setting this to 33 does - i am not sure why, maybe it has something to do with two 1st values used in lib.

So updated optimal solution for now is:
-setting default pos[33] in RegExp.h and REC_STACK_SAVE_MAX=33
-allow user to modify this with pcre_max_stack_offsets: should be >=33 and mutiple of 3
