This problem occurs on g++ version 3.3.2 on Solaris 8. Here is the output from
g++ -v:
Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.8/3.3.2/specs
Configured with: ../configure --with-as=/usr/ccs/bin/as --with-
ld=/usr/ccs/bin/ld --disable-nls
Thread model: posix
gcc version 3.3.2
The strange thing is that this does NOT occur with g++ 3.3.2 on Linux. Here is
the output from g++ -v for it:
Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.3.2/specs
Configured with: ../gcc-3.3.2/configure
Thread model: posix
gcc version 3.3.2
Take the source appended to this message and simply compile (i.e. "g++ -c
virtual.cpp") and the output is the following:
virtual.cpp:23: error: generic thunk code fails for method `virtual void
Foo::log(int, const char*, ...)' which uses `...'
And here is the source:
#include <stdarg.h>
#include <stdio.h>
class BaseClass
{
public:
BaseClass() {}
virtual ~BaseClass() {}
virtual void log(int level, const char *format, ...);
};
class Foo : public virtual BaseClass
{
public:
Foo() {}
virtual ~Foo() {}
virtual void log(int level, const char *format, ...);
private:
};
void Foo::log(int level, const char *format, ...)
{
}
