The following code:
struct A {};
struct B;
template < class TP > struct X : virtual A {
template < class TP2 > X (TP2* ptr) {}
template < class TP2 > X (const X <TP2>) {}
};
struct Y : X <B> {
Y (A* a) : X<B>(a) {}
};
void func1 (X <B>);
void func2 () {
A a;
Y y(&a);
func1(X< A >(&a));
}
produces these messages:
/tmp/ccdER9OM.s: Assembler messages:
/tmp/ccdER9OM.s:125: Error: symbol `_ZN1XI1BEC2I1AEEv' is already defined
on Linux x86, with G++-3.4 branch from a day or two ago.
I'm not sure if the "const X <TP2>" is well formed (it doesn't seem to work in
the non-template form), but the original code wasn't like that, that's a figment
of the automatic testcase reduction I did - so perhaps there's two bugs here.

"const X <TP2>" is well defined. This is the only an ABI bug, but ABI bugs are targeted for 3.4.
Also this is a regression also from 3.3.

oh by the way _ZN1XI1BEC2I1AEEv demangled is X<B>::X<A>(). -funit-at-a-time or -finline are
workarounds as either will cause one of the symbols not to be emitted.
