Hi,

The new test fails at execution on arm and aarch64:

  gfortran.dg/fmt_t_9.f   -O0  execution test
  gfortran.dg/fmt_t_9.f   -O1  execution test
  gfortran.dg/fmt_t_9.f   -O2  execution test
  gfortran.dg/fmt_t_9.f   -O3 -fomit-frame-pointer -funroll-loops
-fpeel-loops -ftracer -finline-functions  execution test
  gfortran.dg/fmt_t_9.f   -O3 -g  execution test
  gfortran.dg/fmt_t_9.f   -Os  execution test

seen on gcc-5 and gcc-6 branches. Maybe I missed it on trunk due to
larger granularity in validations.
