--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
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
