[aspectc-user] Help Needed

[Olaf Spinczyk]

Hi Thiruna,

I'm glad to see that you are experimenting with our prototype. Now, let's see 
what your problem is...

The generated code looks bad:

>    static methodfunctions::__Tjps__advice_0 __tjp_methodfunctions__advice_0
> (, 0);

Here the first argument is missing. I will now try to reproduce the problem 
and fix it (or at least tell you a workaround).

Best regards,

Olaf
