Jan de Mooij 8c93c6e9e8 Bug 1475559 part 5 - Pass a global object to nsScriptErrorWithStack. r=bz
The stack object might be a CCW and we want to make it impossible to get a CCW's global. Now the caller has to supply a same-compartment global object, so we no longer rely on getting the CCW's global.
