           Summary: [ICE] With a simple Algebraic
           Product: D
           Version: D2
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: bearophile_hugs eml.cc



import std.variant: Algebraic;
Spam foo() {
    return Spam.init;
}
struct Bar {
    Spam baz() {
        return Spam.init;
    }
}
alias Algebraic!(Bar) Spam;
void main() {}



DMD 2.063alpha gives:

Assertion failure: 'global.errors' on line 5886 in file 'template.c'



If I swap foo() and Bar{} it compiles:


import std.variant: Algebraic;
struct Bar {
    Spam baz() {
        return Spam.init;
    }
}
Spam foo() {
    return Spam.init;
}
alias Algebraic!(Bar) Spam;
void main() {}

Reduced test case:


template Foo(T) {
    enum size_t Foo = T.sizeof;
}
Spam s1;
struct Bar {
    Spam s2;
}
alias int[Foo!Bar] Spam;
void main() {}
