Description
Copied from 3 year old bugzilla bug: https://bugzilla.xamarin.com/show_bug.cgi?id=28379#c3
Confirmed this is still an issue with Forms version 3.1.0.637273
With a TabbedPage as the main page, and having enough child pages of the TabbedPage so there is a "More" tab, tapping the "More" tab when a page from the "More" tab is already selected causes a crash with the following stack trace:
This is only when each child page of the TabbedPage is wrapped in a NavigationPage.
Removing the NavigationPage wrapper for the child pages (specifically the child pages in the "More" tab) does resolve this issue.
Steps to Reproduce
Load attached test project and run to an iOS simulator or device.
Tap the "More" tab.
Select a page from the list.
Tap the "More" tab again.
Expected Behavior
The list of pages in the "More" tab will be displayed again
Actual Behavior
The app crashes with the above SIGSEV error
