Summary of Problem

Compilation fails with an internal error when a procedure contains a class definition, but only when the procedure has arguments.
This issue shows using version 1.26.0, but it also fails using the main branch version.

Steps to Reproduce

Source Code:

proc broken(ref param1) {
    class InnerClass1 {}
    var obj0 = new InnerClass1();
}

proc not_broken() {
    class InnerClass1 {}
    var obj0 = new InnerClass1();
}

proc also_broken(param1) {
    class InnerClass1 {}
    var obj0 = new InnerClass1();
}

proc main() {
    var arg1 = 0;
    //broken(arg1); //uncommenting this line breaks
    not_broken();
    //also_broken(arg1); //this one also breaks
}

Compile command:
chpl minimal.chpl
Execution command:
None, breaks on compile
