* Comment:
----------
I tried to create a smaller demo of the bug but i could not reproduce
the bug. I always got a message stating:

Foo.h:57: sorry, not implemented: use of `(null)' in template

which refers to the same code as in my original case, which is

DL dl = (DL) resolve(name);


There is no such error, if my BClassFactory::load is defined without
an argument: BClassFactory::load() does the job, it compiles and
works! (of course only for predefined functionnames which is not what
i want though).

I did not have these problems with gcc 2.7.2.3.

I hope this bugreport is useful to you. 

Bye, Marcus
