I'm working with the Regex library and I get the following compiler error: [C++ Fatal Error] regex_replace.hpp(95): F1004 Internal compiler error at 0x99a2402 with base 0x9930000 When I uncomment the line (last function in mydll.cpp): //std::wstring txt = L""; I find this very strange since this line of code doesn't seem to have anything to do with the error I'm getting. I found discussions about similar errors in the archive but nothing that helped me solve my problem. Does anyone know how to solve this? I'm working with Borland C++ Builder 2006.
