Error: no matching case found for: GotoStmt#"error"

[Samuel-Oglegba]

When xform.global_modread(input) is called, where input = GotoStmt#"error" for instance.

How to re-create the Bug

1. Create a file example.pt and add the following code:

     <eval
       input = CODE.GotoStmt#"error";
       XFORM.global_modread(input);
     />

2. run pcg example.pt
3. output: Error: no matching case found for: GotoStmt#"error"
4. expected output: ("","")
