I found it would crash on my x86 device as well.

[Glavo]

Well, it seems that there are no special problems on Linux ARM64, because these problems also occur on Linux x86-64.

[tonsky]

I guess Skia was lying in their docs about never returning null...

[zp-1999]

I also encountered the same problem as you on Ubuntu arm64. How did you solve it?

[tonsky]

What do you mean exactly? Where is the problem occuring? And what is the problem?
