digitalmars.D.bugs - [Issue 22313] New: ImportC: Assigning to a typedefed declaration

https://issues.dlang.org/show_bug.cgi?id=22313

          Issue ID: 22313
           Summary: ImportC: Assigning to a typedefed declaration with a
                    cast expression gives strange errors.
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: major
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: dave287091 gmail.com

The following small, contrived C program fails to compile.

I am not sure what the problem is here. The error messages are nonsensical.

// cast.c
typedef int Integer;
int castint(int x){
    Integer a = (Integer)(x); // cast.c(4)
    Integer b = (Integer)(4); // cast.c(5)
    Integer c = (Integer)x;
    Integer d = (Integer)4;
    Integer e = (int)(x); // cast.c(8)
    int f = (Integer)x;
    Integer g = (int)x;
    Integer h = (int)(4); // cast.c(11)
    Integer i = (int)4;
    int j = (Integer)(x);
    return x;
}

cast.c(4): Error: found `=` when expecting `;` or `=`, did you mean `Integer a
= (`?
cast.c(4): Error: found `=` instead of statement
cast.c(5): Error: found `=` when expecting `;` or `=`, did you mean `Integer b
= (`?
cast.c(5): Error: found `=` instead of statement
cast.c(8): Error: found `=` when expecting `;` or `=`, did you mean `Integer e
= (`?
cast.c(8): Error: found `=` instead of statement
cast.c(11): Error: found `=` when expecting `;` or `=`, did you mean `Integer h
= (`?
cast.c(11): Error: found `=` instead of statement
