Hello !
I'm using Clearscript 5.4 with default V8.
It crashes when trying to write to a property without setter.. but only if I add another global object first, as illustrated with the test below (the fact that it is a PropertyBag does not seems to be relevant). Otherwise it behaves as expected, throwing an exception.
Any idea of what might be happening here ?
