            Bug ID: 60561
           Summary: ICE in gimplify_var_or_parm_decl, at gimplify.c:1721
                    for gfortran.dg/associate_1.f03
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org

A similar backtrace one gets for PR c++/58907.

Compiling the testsuite's gfortran.dg/associate_1.f03 with "gfortran" leads to
an ICE.

The is no ICE if one runs "gfortran -std=f2003 -fall-intrinsics -cpp 
associate_1.f03" as it is done in the test suite itself.

> This should hopefully fix it.

Looks good to me. For the testcase of comment 1, it also gives the expected
run-time diagnostic:

test.f90:19: runtime error: signed integer overflow: 809078955 * 65539 cannot
be represented in type 'integer(kind=4)'
