Stephane Magnenat <[EMAIL PROTECTED]> 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);
}
