I've tried to reproduce your issue using d8 Realms, but don't see the same
error:
$ cat /tmp/realmstest.js
function testFunction(){
let tmpFunc = Function("(function test(\n) {\nreturn 7;\n})\n");
console.log(typeof tmpFunc);
}
testFunction();
let realm = Realm.createAllowCrossRealmAccess();
Realm.eval(realm, 'Realm.global(0).testFunction();');
$ v8 /tmp/realmstest.js
function
function
Could you please file a bug on https://crbug.com/v8 with a reproducing test
case?
