Re: [Boost-users] boost::variant with boost::signals leads to Internal Compiler Error with MSDEV 7.1

your snippit compiles fine using my vs7.1 and the latest from CVS. is there some code needed to instantiate any of this needed to cause the ICE? At Monday 2004-12-20 08:30, you wrote:

Hi

Environment: MS 7.1 compile with MS implementation of STL Boost 1.32.0

Summary:

I get an internal compiler error using boost::variant as a parameter of a boost::signal compiling with MSDEV 7.1, but not with gcc3.3/3.4 or MinGW (3.5).

Does anyone knows a workaround other than not using boost::signals?

Details

Using a signal with a variant of 2 simple classes (see code snippet) leads to an internal compiler error C1001. Using pragma command to turn optimisation off as Suggested by the compiler does not change a thing

Does anyone knows a workaround?

Regards, jom

Here's the bad code snippet:

#include #include #include

#include <vector>

class MessageException : public std::exception { public: MessageException() : std::exception( "Message error" ) {} };

class Message { public: typedef std::vector<unsigned char> Content;

Message(unsigned int p, unsigned char def = ' ') : m_vector( p, def ) {}

const Content& message() {return m_vector;} private: Content m_vector; };

typedef boost::variant MessageVariant;

class TestWrap { public: TestWrap(){}

typedef boost::signal1 MessageSignal; //typedef boost::signal MessageSignal;

void send_signal (MessageVariant& variant) { m_message_signal( variant ); } private: MessageSignal m_message_signal; };
