RE: c++/9942: Function Overload Resolution calls wrong function on variable length parameter lists

[Steve Wadsworth <Steve_Wadsworth at portasystems dot co dot uk>]

Hi Wolfgang,

Right now I'm having great difficulty reproducing this problem.

The files I posted on the problem report are flawed I notice, hence it
appears to exhibit my problem, but it's actually legitimate as I've renamed
one of the function instances with a different name.

I've gone back to my original source code - which is a rather large project
build, with the "ServiceAppLight" and "Logger" classes in a statically
linked library, to see if this was actually causing the compiler to exhibit
the problem and I've now discovered that my original bug report was wrong.

I'm not sure if this is a bug - but I now realise what my original problem
is, and it's not what I reported. It's still function overload resolution,
and it still works OK on the gcc with the previous version of Red Hat Linux,
and with Tru64.

It's where the call to the logEvent function has a character pointer as it's
argument - then it gets a segment violation.

Attached is sample code to exhibit this. 

Regards,
Steve

State-Changed-Why:
    This is one of the rare cases where it would be helpful
    if we would have the original code from which you
    got the preprocessed one. I gather that it is relatively
    small, but I can't recreate the va_start calls etc.
    Could you possibly send them to me?
    
    Thanks
      Wolfgang
