--- Comment #3 from Thomas Koenig <tkoenig at gcc dot gnu.org> --- Could you simply post the complete C++ source code that you used in the original example? This has the advantages of a) making it easier to modify (for a non-C++-person such as me) and b) of conforming to the gcc bug reporting guidelines at https://gcc.gnu.org/bugs/#need . Thanks!
