Bug #: 51812
Summary: Virtual public inheritance leads to "undefined
reference" in header files.
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: bredelin@ucla.edu

The c++ file that has linker errors.
Hi,
Using gcc 4.7 causes new linker errors that are not present in e.g. 4.5, 4.6,
or clang. These linker errors make it impossible to use header files that do
not fully define some classes entirely in the header file.
The errors look like:

All the errors go away if you change class alphabet to not have virtual public
inheritance, by removing the word "virtual".

virtual char* print() const;
};
class alphabet: virtual public Object{};
class Nucleotides: public alphabet {};
class DNA: public Nucleotides {

This testcase requires thunks and virtual inheritance.
