Runtime Error on PCRE library, really need help!
-
I'm trying to port the FreeLing (Natural Language Processor) from linux to windows platform. The FreeLing used the PCRE library for reg-ex. The FreeLing is built on C++ (normal STL) langauage. And I know that it's required a C++ Wrapper for PCRE. BTW, FreeLing have included C++ Wrapper in their project. I'm trying to use its built-in wrapper because it is modify to suitable for their code. If I change to another wrapper for PCRE, I think I could have a lot of work to modify the wrapper. Let's see the error here. The Runtime error occur when the "void clone();" in "regexp.h" in FreeLing is running. Here's the part of "regexp.h" in FreeLing. The error is on "pcre_fullinfo(y.re, y.pe, PCRE_INFO_STUDYSIZE, &size);" Line.
private: void clone(const RegEx &y) { size_t size; if (!y.re) return; pcre_fullinfo(y.re, 0, PCRE_INFO_SIZE, &size); re=(pcre*) new char[size]; if (!re) { throw "not enough memory"; } else { std::cout << std::endl << "**** Making new re pointer Allocation successful.. *****" << std::endl; } memcpy(re, y.re, size); // Run time error on pcre_fullinfo(); pcre_fullinfo(y.re, y.pe, PCRE_INFO_STUDYSIZE, &size); pe = (pcre_extra *) new char[size]; if (!pe) throw "not enough memory"; memcpy(pe, y.pe, size); substrcount = y.substrcount; ovector = new int[3*substrcount]; matchlist = NULL; }And the error in pcre_fullinfo(); in PCRE.C is below.
