Hello, I've an application which runs nicely on linux (Qt 4.7.3 gcc 4.1.2 32 bits) and I want it to run on windows XP 32 bits. So I've been built it inside eclipse (not my choice, it is part of a bigger C++ project), everything was fine until I want to execute it. It crashed poorly giving me the following exception:
terminate called after throwing an instance of "std::logic_error" what() : basic_string::_S_construct NULL not valid. I've checked that all of my char* are not NULL before casting them into QString. Anyway running into debugger tells me it's the following line which seems to be the culprit: CommandLinkPOS2::CommandLinkPOS2(const QString& serverName,unsigned short port) : CommandLink(QString(POS2_CMD),serverName,port) And especially in qtring.h at line : inline QT_ASCII_CAST_WARN_CONSTRUCTOR QString(const char *ch) : d(fromAscii_helper(ch) The parent constructor is called well but it seems the exception is launched after it (the POS2_CMD symbols is #define POS2_CMD "POS2"). The build on windows is done against Qt 4.7.3 with mingw 5.1.8 (gcc 4.5.2). The gcc version is newer than the one used on linux, but I'd not expected such problem. There is one more strange behaviour. The executable produced runs as expected under a cygwin environment but it launches an exception under cmd.exe or if I double click it. Have you any clue of what is going on here. Any hint would be greatly appreciate because I'm stuck.
