      Windows

      Description

      To reproduce, run simple browser example (debug build) and repeatedly click "Developers" link in qt.io. It seems completely random and may take many tens of clicks to occur.

      It shows a dialog that the render process crashed. Pressing Yes to reload the page, crashes the example with this printed to the output:

      [21636:22496:0821/103950.169:FATAL:network_context.cc(969)] Check failed: false.
