[BUG] Crashes on Android

Description

I'm using mapping library Mapsui, error occurs randomly when moving the map, noticed some of the crashes even with map staying still.

Code

I also noticed an error with address 0x40, and possibly 0x1130 (no .so file path in this case) - can't find the stack trace now.

This might be a duplicate of #1121

Looking at the stack traces in the mapsui issue, this looks a bit similar. The original issue was macOS, but maybe this is just one example.

Yes, the description seems to fit. The very same crash is also happening on iOS, already told the poster of Mapsui/#865 to post the stack trace here.

I have just published the PR (#1180) NuGet (1.68.2-pr.1180.4) to the preview feed: https://aka.ms/skiasharp-eap/index.json
This contains the fixes for macOS, iOS and Android. More platforms coming soon.

Give that a go and let me know if it fixes the crashes.

[mattleibow]

Just pushed all the packages (preview 45) to NuGet.org.

Hey folks, it has been a long time coming and thanks to all the folks with your repros, samples and stack traces I think we have finally managed to fix those pesky crashes - at least the ones we know about. I have just pushed 1.68.2-preview.50 to NuGet so let me know if this fixes all the crashes you have ever had 😄
