Bug ID: 93701
Summary: ICE on associate of wrongly accessed array
Product: gcc
Version: 9.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: simon_brass at gmx dot de
Target Milestone: ---

Reproducer file for the ICE using associate and array statements.
I've got the following ICE report appearing in the attached file.
* Error message
f951: internal compiler error: find_array_spec(): Missing spec
* Source Code / Reproducer
The source code *is* erroneous, therefore, should not compile, however, it
should fail with an error message.
The error appears within:
> associate (state => obj%state(TEST_STATES))
> state%a = a
> state(TEST_STATE)%a = a
> end associate
where state can be either of intrinsic or derived type.
The compiler should complain on the third line and TEST_STATES, the latter
should be TEST_STATE.
Exchanging the second and third line, or correcting the name of TEST_STATES to
TEST_STATE (removed the S at the end), leads then to a correct error message by
the compiler.
* Build command
gfortran -c ice-gfortran.f90 -o ice-gfortran.o
Also, tried:
gfortran -Wall -Wextra -c ../test/ice-gfortran.f90 -o ice-gfortran.o
gfortran -Wall -Wextra -fno-strict-aliasing -fwrapv -c ../test/ice-gfortran.f90
-o ice-gfortran.o
* Output of gfortran -v
Using built-in specs.
