Any chance you could backport for 4.8 Yvan? Do you want me to do it? Or are the
release manager against a 4.8 backport?

Best regards,

A simple testcase:

[hjl@gnu-mic-2 delta-fortran]$ cat foo.f90
      SUBROUTINE DTRSM ( NN, NB)
         DO 50 J = NN, 1, -NB
   50    CONTINUE
      end
[hjl@gnu-mic-2 delta-fortran]$
/export/project/git/gcc-regression/master/217349/usr/bin/gfortran -ffixed-form
-ffixed-line-length-132 -DSPEC_CPU2000_LP64 -ffast-math -S  foo.f90 -O2
foo.f90:4:0:

       end
 ^
Error: non-trivial conversion at assignment
unsigned int
integer(kind=4)
_13 = _7;
foo.f90:4:0: internal compiler error: verify_gimple failed
