Bug ID: 87154
   Summary: Internal compiler error: in gimplify_expr, at
gimplify.c:12215
   Product: gcc
   Version: 7.3.1

This file triggers the crash

When compiling the attached source file (originally from a large project,
reduced to just the lines causing the crash) an ICE is triggered.

Confirmed in both gcc 7.3.1 and 7.3.0.

Example compiles correctly in Intel fortran and PGI fortran.

A slightly modified source file also attached using an explicit pointer instead
of an ASSICATE compiles without errors.

Stack trace:
gfortran -c crash.f90

crash.f90:31:0:



   args = str_split(param,',')
