[Mingw-users] Lost C++ exception

[Olivier G. <li...@sa...>]

I am encountering a problem where I rise a C++ exception, which consists in a
class that sub-subclasses std::exception. The constructor of this exception
class is properly called. However, my catch statement is never reached, and the
application freeze, entering a dead loop that eats all cpu.

QtCreator/gdb doesn't tell anything, no source line, no error message, nothing.

The application is multi-threaded, but the throw/catch sequence happens in a
single (worker) thread.

The general idea:

class BaseException: public std::exception
{
public:
    BaseException(std::string message) throw()
    {
        this->message = message;
        DEBUG("Exception: %s", message.c_str());
    }
    ~BaseException() throw() {}

    virtual const char* what() const throw()
    {
        return message.c_str();
    }

protected:
    std::string message;
};


class NotEnoughFramesError: public BaseException {
public:
    NotEnoughFramesError(std::string filename) throw()
            : BaseException("Not enough frames in sample file: " + filename) {}
};


This code works fine on gcc/linux.

Is there anything special I should be aware of when dealing with exceptions in
mingw?
