--- Comment #1 from janus at gcc dot gnu.org ---
I can confirm this ICE with every gfortran version from 4.7 to current trunk.
The test case as provided compiles fine, but when uncommenting one of the
marked lines the ICE appears.
The backtrace on current trunk is:
print *, ' dot_1d, generic call = ',this%dot_no_override(x1d,y1d) !
causes compiler segfault
