507501 - Vector.map does not return the correct vector type

Status: VERIFIED DUPLICATE of bug 513095

(Tamarin Graveyard :: Virtual Machine, defect, P2)

Description

[Chris Peyer]

as:
function convertToUpper(item:String, index:int, v:Vector.<String>):String {
return item.toUpperCase();
}

var vec:Vector.<String> = Vector.<String>(['one','two']);


var vec2:Vector.<String> = vec.map(convertToUpper);
trace("vec2 = " + vec2);
trace(vec is Vector.<String>);

trace(vec.map(convertToUpper) is Vector.<String>);

Actual:
TypeError: Error #1034: Type Coercion failed: cannot convert []@4ec289 to __AS3__.vec.Vector.<String>.
at global$init()

Expected:
The vector returned by .map is a Vector.<String>

Only happens when compiled w/o -AS3 flag

513095, 507501, and 509502 all all symptoms of an underlying SNAFU in the Vector implementation.  Fix is attached to 513095.
