This is a bug :-(

The internal signature of "char* getB ()" is stored as "char * getB()". Thus, 
you can match functions returning a pointer to a character like this:

 pointcut pc_ClassX_GETTER() =  execution("char * ClassX::get%()");
(the space between "char" and "*" is important!).

This is an unintended behavior of the AspectC++ matching routine and will be 
fxed in future releases. You can savely use the workaround "char *" now and 
later, because this will be supported as well.

BTW, we have the same problem and workaround with "char &".

Yours,

Olaf
