The following testcase asserts on ionmonkey revision 5a04fd69aa09 (run with --ion -n -m --ion-eager), tested on 64 bit: var optionNames = options().split(','); for (var i = 0; i < optionNames.length; i++) { var optionName = optionNames[i]; options(optionName); var lfcode = new Array(); lfcode.push("var g = newGlobal('new-compartment');\ g.eval('(' + function () { dbg = new Debugger(debuggeeGlobal);\ adbg.onExceptionUnwind = function (frame, exc) {}; } + ')();');\ "); var file = lfcode.shift(); if (file == undefined) { break; } loadFile(file); } function loadFile(lfVarx) { try { evaluate(lfVarx); } catch (lfVare) { } }

This is a bogus assert, made more bogus by the fact that it changes the options disabling -n and using unsupported code paths - I'll just dupe this against bug 724751 which will remove the dummy oracle.
