Bug ID: 78395
Summary: [OOP] ICE for operations with polymorphic variables
Product: gcc
Version: 6.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: cmacmackin at gmail dot com
Target Milestone: ---

Minimal code producing ICE.
While trying to produce a minimal example for an issue I've been having with
gfortran seeming to misidentify return types when I chain togethor certain
type-bound operators, I came across this ICE. I've attached the code which
produces the ICE. gfortran seems to run into trouble when parsing return types
for line 132. When I perform the same operations using non-polymorphic
variabels (as in line 131) there is no issue.
I am using a self-compiled gfortran-6 binary (compiled against the OpenCoarrays
library, although I'm not using any coarray features). Running "gfortran -v
minimal-abstract.f90" produces
Driving: gfortran -v minimal-abstract.f90 -l gfortran -l m -shared-libgcc
Using built-in specs.
