Hi everyone,

I found out an inconsistency if we try to evaluate a scoped function block after an eval statement. If I remove the first line (eval line), JSC works as expected.

Version: 235318
O.S: MacOS High Sierra Version 10.13.6

step to reproduce:
eval("if (false) function _f() {} else function f() { return 1; }");
{
   function f() {
      return 2;
   }
}

print(f())

atual result: 
1

expected result:
2

V8, Chakra and SpiderMonkey works as expected
