System: Linux lexus 2.4.4 #1 Fri May 18 18:13:11 PDT 2001 i686 unknown
Architecture: i686

	
host: i686-redhat-linux-gnu

>Description:
	g++ 3.0 dies with "Internal error: Segmentation fault" when compiling 
	following code:

class test
{
    public:
	typedef bool (test::*ResponseFunc)(char*);
	typedef bool RF(char*);

	struct Command {
	    ResponseFunc respFunc;
	};


	RF setLosSwd;
	RF getLosSwd;
	RF printHelp;

	static Command d_cmdTable[];
};

test::Command test::d_cmdTable[] = {
    {&test::setLosSwd},
    {&test::getLosSwd},
    {&test::printHelp}
};

>How-To-Repeat:
	Preprocessor output is the same as above.
>Fix:
	If I don't use typedef of RF the problem is gone, i.e., following
	code compiles fine. gcc-2.95.3 does not have this bug.


class test
{
    public:
	typedef bool (test::*ResponseFunc)(char*);
	typedef bool RF(char*);

	struct Command {
	    ResponseFunc respFunc;
	};


	bool setLosSwd(char*);
	bool getLosSwd(char*);
	bool printHelp(char*);

	static Command d_cmdTable[];
};

test::Command test::d_cmdTable[] = {
    {&test::setLosSwd},
    {&test::getLosSwd},
    {&test::printHelp}
};
