[Impeller][iOS] : crashes with EXC_BAD_ACCESS in impeller::Tessellator::TessellateConvex on latest stable version #149646
Description
Steps to reproduce
- Using the flutter_map library version 7, create a polygon with a hole
- Zoom out a long way from the polygon (this will trigger polygon simplification)
(This is also logged against flutter_map as bug: fleaflet/flutter_map#1903)
Expected results
App should display a zoomed out polygon
Actual results
On iOS the application crashes with EXC_BAD_ACCESS in impeller::Tessellator::TessellateConvex.
This can be reproduced reliably on both physical iOS devices and the iOS simulator.
On other platforms (tested on Windows, MacOS and Android) the crash does not occur.
