Hi everyone,
there is an inconsistency in JSC if a switch statement with only one case block evaluation that could be not reached.

version: 235318
OS: Ubuntu 16.04 x64

steps to reproduce:
{ function f() { return "f 0"; } }
switch (1)
{
  case /0.0/gi:
    function f() {
       return "f 1";
    }
    break;
  default: 
    break;
}
print( f() );

Actual results:
f 1

Expected results:
f 0

V8 and SpiderMonkey works as expected.
