Goals

Use realm in device while remote debugging

Actual Results

While not making any read or write, (actually happens moments after writing data and being queried), the app suddenly crashes at physical iOS device at line 41 in file RealmJS.xcodeproj/RealmJS/JSC/jsc_protected.hpp.

~Protected() {
        if (m_context) {
            JSGlobalContextRelease(m_context);
        }
    }

NOTE: Only happens while remote debbuging

Steps to Reproduce

Run on device, debbuging mode.
After crash some data happens to be missing.

Code Sample

// TabNavigation.js

export let realm

class TabNavigationScreen extends PureComponent {
  async connectRealm() {
    try {
      realm = await openRealm()
    } catch (error) {
      console.warn('Realm error', error)
    }
  }
}

// realm/index.js
export const openRealm = () => {
  return Realm.open({
    schema: [
      OfflineServiceSchema,
      OfflineUnitServiceSchema,
      OfflineUnitServiceStatusSchema,
      PlagueCountSchema,
    ],
  })
}

<!---
Please provide a code sample or test case that highlights the issue.
If relevant, include your model definitions.
For larger code samples, links to external gists/repositories are preferred.
Full projects that we can compile and run ourselves are ideal!
