@swift-ci create

belkadan · 2018-06-28T01:53:25Z

This is a materializeForSet for a rather boring variable,

class Main : WOComponent {
  // …  
  public var demo : String? = nil
  // …
}

The deserialization code is complaining that the function type doesn't match up, but both types dump as this:

(sil_function_type type=@convention(method) (Builtin.RawPointer, @inout Builtin.UnsafeValueBuffer, @guaranteed Main) -> (Builtin.RawPointer, Optional<Builtin.RawPointer>))

@rjmccall, any ideas?

belkadan · 2018-06-28T01:54:26Z

Removing the public makes everything happy. Hm.

rjmccall · 2018-06-28T04:39:34Z

SILFunctionTypes are always canonical and I don't think we hide anything when printing them, so the mostly likely thing is that the nominal component type (Main) is actually a different type for some reason.

belkadan · 2018-07-03T01:46:44Z

Aha, this module has both a Main.swift and a main.swift, which would be fine…except that SwiftPM accidentally puts the intermediates for those two in the same place on a case-insensitive filesystem. @aciidb0mb3r, you have the dup for this, right?

belkadan · 2018-07-03T01:47:30Z

(There is a separate "the compiler shouldn't crash" aspect, but short of noticing that we're reading the same file even though we went through two different paths, I'm not sure how to catch this in any meaningful way.)
