OpenFileDialog.ShowAsync segfaults on Linux #2817

PJB3005 · 2019-08-08T07:27:15Z

this.FindControl<Button>("Da").Click += async (_, __) =>
{
    var dialog = new OpenFileDialog();
    var file = await dialog.ShowAsync(this);
    Console.WriteLine(file[0]);
};

Causes a segfault inside GTK's drawing code.

Please, install debug symbols for libfreetype and libcairo and try that again.

Judging from the stack trace, libfreetype tries to call something in libSkiaSharp, which it shouldn't be doing under any circumstances. The only possible reasons for that I can think of are:

some symbol was incorrectly resolved via dynamic library loader (on Linux imported symbols aren't bound to library names)
Skia somehow registered a callback in libfontconfig and libfreetype tried to execute it

kekekeks · 2019-08-08T07:46:24Z

I've checked the libSkiaSharp.so file and it seems to be exporting FT_* symbols it's not supposed to. Filed a bug in SkiaSharp

Roflincopter · 2019-12-30T15:36:28Z

This should be fixed in Skia.Sharp 1.68.1, When can we expect Avalonia to target a fixed version of Skia.Sharp?

kekekeks · 2019-12-30T15:40:33Z

master branch is already using it

josegomez · 2020-04-13T17:48:50Z

@kekekeks at all, has this been merged and pushed out yet? Having the same issue in Manjaro Linux

Gillibald · 2020-04-13T17:54:07Z

FreeType symbols should no longer be exported so there might be a different cause. The current release still uses Avalonia's custom build so if possible try current master.

kekekeks · 2020-04-13T17:59:53Z

@josegomez are you checking with master or 0.9.x-based build?

josegomez · 2020-04-13T18:03:51Z

I'm using the latest published nuget @kekekeks 0.9.7
The issue may not be this exact one it is happening on the same place
I haven't been able to get a good log yet because the seg fault blows away any logging I've put in.

josegomez · 2020-04-13T20:27:48Z

Just replicated this on manjaro linux with Avalonia 0.9.7
Here's the Trace if it Helps
