Hi All,
I ran the polyhedron testsuite with the patched gfortran-13.0.1 and 7.4(as
used in the posted Linux test). The timings are comparable except for
rnflow.f90.
As noted below, rnflow.f90 hangs with the unpatched mainline at -O3 but
runs successfully at -O2.
I presume that this is a serious regression since it involves optimization?
Which component should I post it against?
Regards
Paul

****rnflow hangs without patch as well. Seems to be a rather serious
regression.
gets stuck with -O3 in the loop starting at line 3566 in subroutine cptrf2
