            Bug ID: 114548
           Summary: gm2 fails to identify variable in a const expression
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: modula2
          Assignee: gaius at gcc dot gnu.org
          Reporter: gaius at gcc dot gnu.org
  Target Milestone: ---

As reported on the gm2 mailing list.

gm2 fails to identify the specific variable within a const expression.  It
gives an error for the whole expression rather than the sub expression in
error.
For example:

$ cat testcmplx.mod
MODULE testcmplx ;

CONST
   foo = CMPLX (r, i) ;

VAR
   r, i: REAL ;
BEGIN

END testcmplx.

$ gm2 -fiso testcmplx.mod 
testcmplx.mod:4:8: error: In program module ‘testcmplx’: in assignment, cannot
assign a variable to a constant ‘foo’
    4 |    foo = CMPLX (r, i) ;
      |    ~~~~^~~~~~~~~~~~~
testcmplx.mod:4:4: error: designator ‘foo’ is declared as a CONST
    4 |    foo = CMPLX (r, i) ;
      |    ^~~

it could identify r and i as variables.
