(In reply to H.J. Lu from comment #0)
It only happens when running
make check-gfortran RUNTESTFLAGS=dg.exp=assumed_rank_7.f90
--target_board='unix{-march=corei7\ -fno-backtrace}'
Can you confirm that it is now fixed? Not that we only fixed part of the
problem.

gfortran.dg/assumed_rank_7.f90 has been changed by r208668
and I can't reproduce it anymore.
