Embedding v8 6.7, open to upgrade if necessary.
I modified v8 shell.cc to experiment with the new Module API and am trying
to figure out how to handle error conditions while resolving a module.
If the resolve callback calls v8::Isolate::throwException, I get:
#
# Fatal error in ../../src/api.cc, line 2325
# Check failed: self->status() >= i::Module::kInstantiated (0 vs. 3).
#

If resolve callback returns a module not containing the imported functions:
V8 version 6.7.288.52 [sample shell]
> import { square, diag } from 'lib';
(shell):1: SyntaxError: The requested module 'lib' does not provide an
export named 'square'
import { square, diag } from 'lib';
^^^^^^
SyntaxError: The requested module 'lib' does not provide an export named
'square'

How is ResolveCallback supposed to handle these error conditions to avoid
v8 crashes?
If I upgrade to the latest stable v8 version, is it going to help?
Thanks a lot in advance!
