 No -- but I will if you tell me how best to do that.

 It seems that g++ emits two identical copies of the constructor
 for B from the same source lines. When gdb sets the breakpoint
 at the specified line it chooses one of those copies but gcc happens
 to call the other copy. Thus the breakpoint is never reached.
 This means that this is probably a gdb bug (gdb should set two break
 points) but someone should verify that the debugging information
 is really ok.
 
     regards  Christian

State-Changed-Why:
    I rechecked, with gdb 5.1.1: this still happens with 3.2.2pre,
    3.3pre and 3.4 mainline. It worked with 2.95, though, so this
    is a regression.
