420839 - DVG of |yield| expression seems to fail

Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Jesse Ruderman]

js> for (let i in (function() { (yield 1).a=3 })()); 
typein:1: TypeError: (void 0) is undefined

Should be: TypeError: (yield 1) is undefined

Comment 1

[Jesse Ruderman]

Or maybe this is fine, and error messages are allowed to use uneval sometimes rather than decompiling an expression.

Comment 2

[Luke Wagner [:luke]]

js> for (let i in (function() { (yield 1).a=3 })()); 
typein:1:29 TypeError: undefined has no properties

Not great, but not wrong.
