New issue 3995 by [email protected]: Compilers disagree about source
position of "throw new Error()"
https://code.google.com/p/v8/issues/detail?id=3995
The optimizing compiler and full-codegen disagree about the location
associated with the exception message for a "throw new Error()" clause. The
full code places is at the "new" location, whereas both Crankshaft and
TurboFan place it at the "throw" location.
$ ./out/ia32.debug/d8 -e --allow-natives-syntax "function f() { throw new
Error(); } f();"
unnamed:1: Error
function f() { throw new Error(); } f();
^
Error
at f (unnamed:1:22)
at unnamed:1:37
$ ./out/ia32.debug/d8 -e --allow-natives-syntax "function f() { throw new
Error(); } %OptimizeFunctionOnNextCall(f); f();"
unnamed:1: Error
function f() { throw new Error(); } %OptimizeFunctionOnNextCall(f); f();
^
Error
at f (unnamed:1:22)
at unnamed:1:69
