As of iOS 11, these memory leaks began surfacing in our kiosk iPad application (a tablet app that runs 24/7).

Crashes have been found on the following:
- JSC::Heap::runNotRunningPhase(JSC::GCConductor) 
  http://crashes.to/s/b9212ed75c4
- JSC::Heap::runCurrentPhase(JSC::GCConductor, JSC::CurrentThreadState*)
  http://crashes.to/s/23cd9a6ab40
- JSC::Heap::finishChangingPhase(JSC::GCConductor)
  http://crashes.to/s/3abc177f424

Could you please provide a reproducible test case, or at least leaks tool results from Instruments? 

It’s not clear why you are saying that these crashes are in some way related to memory leaks, so it may be best to file a separate detailed report for each of the crashes. At the very least, we’ll need full crash logs, but chances are that repro cases will be necessary.
