Stephane Magnenat <nct@ysagoon.com> reports:

When I try to compile C++ code with virtual inheritance and variable number of 
argument method, the compilation fails with the following message :

bugreport.cpp:35: generic thunk code fails for method `virtual void
   Virt::p(const char*, ...)' which uses `...'

It is working fine with gcc 2.95.x



#include <stdio.h>
#include <stdarg.h>

class Base
{
public:
	Base() { }
	virtual void p(const char *format, ...)=0;
};

class Der1: public virtual Base
{
public:
	Der1():Base() { }
	virtual void p(const char *format, ...)=0;
};

class Der2: public virtual Base
{
public:
	Der2():Base() { }
	virtual void p(const char *format, ...)=0;
};

class Virt:public virtual Der1, public virtual Der2
{
public:
	Virt():Der1(),Der2() { }
	virtual void p(const char *format, ...)
	{
		va_list arglist;
		va_start(arglist,format);
		vprintf(format, arglist);
		va_end(arglist);
	}
};

int main(int argc, char *argv[])
{
	Virt v;
	v.p("Hello %d\n", 10);
}
