Probably because you used a bool(*)(const A&) instead of bool(&)(const A&)?
Pointer to functions are generally better behaved than references to 
functions.

Whatever the problem was, it appears to be fixed in the trunk.
It errors through 1.37, I never downloaded 1.38 or 1.39, so I
didn't check them.  My best guess is that it was fixed by
