           Summary: internal compiler error: in conv_function_val, at
                    fortran/trans-expr.c:3792
           Product: gcc
           Version: 8.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org

A source file to reproduce the bug

The bug occurs when you have a module with some name (lets name it init) and it
uses a module with an aliased subroutine or function with the same name (init)
- see the attached source file. 

-The command command line that triggers the bug (with -v and -save-temps
flags):

gfortran-8 -v -save-temps -o test test.f90

-The the compiler output:

Driving: gfortran-8 -v -save-temps -o test test.f90 -l gfortran -l m
-shared-libgcc
Using built-in specs.
