1130792 - Boolean.prototype.valueOf resolves to AS3::valueOf instead of public::valueOf, leading to a wrong result

Status: RESOLVED INCOMPLETE

(Firefox Graveyard :: Shumway, defect)

Description

[Till Schneidereit [:till]]

This might well not be fixable. It's caused by us installing the AS3 traits into the normal prototypes for primitive builtins. That leads to Boolean.prototype having definitions for both AS3::valueOf and public::valueOf, and we go for the AS3 version.

For some reason that I cannot figure out at all, this is actually not true in the shell: there we correctly resolve to public::valueOf, with the interpreter and both compilers. In the browser, we do the wrong thing always.

I'm not sure this matters at all as I have a hard time thinking of any content that would actually depend on this: it should behave the same absolutely everywhere *but* for Boolean.prototype itself.
