As Andrew said, this is not a bug, see

You can force it to be parsed as a variable declaration with A a((B()))

A a(B()); is a function declaration and not a variable declaration.  This is

one of the ambiguities of the parsing which the C++ standard decided it was a

function rather than a variable.
