Created attachment 17158 [details] patch -- renames make it look *much* bigger than it is
Comment on attachment 17158 [details] patch -- renames make it look *much* bigger than it is One typo. + (jsRegExpExecute): Use new/free instead of pcre_malloc/free. Removed unused + start_match field from the match block. You meant new/delete I believe. There is also one place where you use fastMalloc/fastFree instead of new/delete. I am not sure if you want to make the change. r=me. You may want to test on windows first though.
Tested on Windows and made appropriate fixes. Committed revision 27686.
