497371 - Error message for invalid vector class does not indicate what the problem is.

Status: VERIFIED WORKSFORME

Given the following as:

var s:String = 'asdf';
var v:Object = new Vector.<s>();

tamarin will throw a verifyerror:
VerifyError: Error #1107: The ABC data is corrupt, attempt to read out of bounds.
	at global$init()

This does not help the user know what the problem is.  A more specific error message would be much more informative.

That verifier error is rather commonly (mis)-used to signal a miscellaneous error in the ABC.  Compiling the .as file in -strict mode does provide a better diagnostic:

tharwood-MacBookPro:mybuild tharwood$ asc -strict ~/sandbox_as/bugs/497371.as

[Compiler] Error #1120: Access of undefined property s.
   /Users/tharwood/sandbox_as/bugs/497371.as, Ln 2, Col 20: 
   var v:Object = new Vector.<s>();
