SIGSEGV due to Gtk file chooser on ArchLinux

[balert]

Version

version_1.42.0-alpha3-91-g5a707a66b

Operating system type + version

ArchLinux x64

Behavior

SIGSEGV when opening file chooser dialog.

gtk_file_chooser_dialog_new (libgtk-x11-2.0.so.0) appears in coredump. I believe the Slic3r is not compatible with my (ArchLinux) Gtk library?!

Slic3r crashes when opening .stl file, but drag and drop into Slic3r works fine. I can use "Send to printer", so Slic3r is basically still "usable" for me by avoiding file chooser dialogs :-)

Hi, does this still happen with a more recent alpha?
Can you provide a backtrace?
Thanks!

[balert]

yes, I've just tried tags/version_1.42.0-alpha6. Does this help:

@balert Thanks. I can't say for sure but it seems like memory allocation callbacks are botched for gtk in libpng. I'll see what can be done...

[bubnikv]

What happens if you download the .bz2 archive instead of the appimage, you remove the libpng from the unpacked directory and then you run Slic3r?

It may be, that the bundled libpng12 fights with the one installed on your system.

[balert]

yes, it works from the bz2 archive. that's my current work around.

[vojtechkral]

@balert We've removed a direct libpng dependency. Would you please re-test with the following AppImage?

Slic3rPE-1.42.0-beta1+78-linux64-full-gd209aaa-201903281040.tar.gz

[balert]

@vojtechkral the AppImage did apparently work well. Had no crash due to file chooser anymore. Great work. Thanks!

[bubnikv]

Great. So the crash was likely due to the libpng bundled with Slic3r not to be (sic!) binary compatible with the libpng of the same version installed on your system.

We now link the libpng statically only, so this issue is gone. Thanks for testing.
