--- Comment #1 from anlauf at gcc dot gnu.org ---
Confirmed.
A look at the tree dump shows a funny expansion of the array section in
the data transfer (write statement). It appears that some optimization
of the transfer of arrays is attempted, but the stride looks wrong.
Replacing
WRITE (0,*) vertices_pointer%vlon(1:)
by any of the following produces different - working - output:
WRITE (0,*) [vertices_pointer%vlon(1:)]
WRITE (0,*) (vertices_pointer%vlon(1:))
WRITE (0,*) (vertices_pointer%vlon(i),i=1,size(vertices_pointer%vlon))
And - as reported - why should the addition of a (dead) pointer assignment
after the write change the way the array section is expanded?
Looking at older gfortran version, all tested seem to fail.
And with the dead pointer assignment uncommented, gfortran-7 ICEs.
