After updating project dependencies complier started crashing, cannot trace it down inside a large projects. System records two similar crashlogs, both attached. Any suggestions on pinpointing this?

Infinite recursion in the type checker. @rudkx, any ideas?

Don't have any reproducibles for this now, but the issue was with generic method whose argument was passed to non-existing invocation, here's an example:

// KeyboardHotkey(value:) signature got changed to KeyboardHotkey(:) – here it doesn't exist, so perhaps type checker tries to find the declaration and goes in recursion.
return self.makeBindingTarget({ $0.hotkeyRecordArea = KeyboardHotkey(value: UInt64($1)) })
