Description

[Christian Holler (:decoder)]

The following code asserts on TI tip (run with -m -n -a), tested on 64 bit:

function f0(i) {
  switch(i) {
  case "a":
  case { TITLE: false, VERSION: false }('test')
 : 
  }
}
new TestCase(SECTION, 'switch statement', f0("a"), "ab*");

RegisterAllocation::synced, used to determine whether we need rejoin code when jumping from after a stub call to a join point, did not account for registers from inline parents that need to be preserved at the join point.
