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, ...)
{
}
