            Bug ID: 94925
           Summary: Undesired runtime warning message
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: siteg at mathalacarte dot com
  Target Milestone: ---

Just upgraded to GNU Fortran (GCC) 10.0.1 20200328 (Red Hat 10.0.1-0.11), a=
nd
am getting this warning at runtime:
"Fortran runtime warning: An array temporary was created"
This did not happen in the past.  I have tried adding the flags
-fcheck=3Dno-array-temps -Wno-array-temporaries
to no effect.  These occur in a large program where these temporary arrays =
are
used for debugging information that would not be used in production.  I have
not managed to create a small program that illustrates the problem.  I'm ho=
ping
that the fact that this problem occurred between the 9.3.1 compiler and the
current one may help in getting it tracked down.=
