This seems to be caused by the unit-at-a-time changes, the following program
compiled cleanly with -O2 at version 138139 but gives an error message when
compiled (with -O2) at version 138140. I found it on IA64 HP-UX but was able
to reproduce it on x86_64 Linux.
class A { };
class B : public virtual A { };
class C { public: virtual class A* foo() const; };
class D : public virtual C { public: virtual struct B* foo() const; };
class B* D::foo() const { return 0; }
-----
x.cpp:7: error: 'B* *.LTHUNK1() const' aliased to undefined symbol
