Summary0006080: Every attempt to load a texture will trigger a SIGSEGV signal caught: 11
DescriptionIts all about Linux version

Everytime when I try create new object, prefab etc or just hold left mouse button and start paint got this:

SIGSEGV signal caught: 11

(darkradiant:6595): Gdk-WARNING **: 18:44:06.095: The program 'darkradiant' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
(Details: serial 4678 error_code 9 request_code 155 (unknown) minor_code 4)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

P.S. already try nvidia proprietary driver and under open source nouveau with same result, so I suppose this is not a driver issue
The Dark Mod 2.10 works like a charm and the darkradiant ver 2.* too
Steps To ReproduceStart darkradiant, hold left mouse and try to paint something on main window or create new object, prefab etc

It appears you're using the newer wxWidgets 3.2 release, may I ask which distro you're on? It's possible that this is something related to this new release, we haven't had a chance to fix it yet (if I'm not mistaken).

I am using Arch Linux
I also try compile with (3.1.7) with same result
unfortunately arch drop support wxwidget with gtk2

This is the same thing I encountered, wx 3.2 and 3.1.7 both had the issue. I had narrowed the issue down to texture loading. It crashes when you create a brush, try to view a model, etc. It doesn't matter which texture format, each of the loaders crash when they try to write the decompressed image into the RGBAImage. That's as far as I got when debugging it.

@DavyJones if you're interested, I'm about to release a flatpak version. Keep an eye on in the next day or two.

I definitely take a look on this, thx @jonri !

I looked into this, and I believe something is linked incorrectly. It appears there is a class RGBAImage in both the libradiantcore binary as well as the /usr/lib/ module (in Arch).
The GDB stacktrace already reveals that something weird is going on:

- 0 0x00007ffff6ef5188 in typeinfo for FontRealised () at /usr/lib/
- 1 0x00007fffeba14aaa in image::LoadBMPBuff(stream::PointerInputStream&, unsigned long) () at /usr/local/bin/../lib/darkradiant/modules/
Nothing in that LoadBMPBuff method is ever calling anything near the Scintilla library. On my end, I get the same when loading TGA files, and both code paths sooner or later try to access a member of the RGBAImage class defined in DarkRadiant's libs/RGBAImage.h.

The compiler doesn't complain about any duplicated class, because RGBAImage is a private implementation detail in the scintilla sources (compare wxWidgets sources, file src\stc\scintilla\src\XPM.h), and DarkRadiant's sources cannot even include that XPM.h file. But the shared module exports the RGBAImage symbol, and I suspect the linker is connecting the wrong vtable in ibwx_gtk3u_stc:

[greebo@FLAXN:~][2]$ readelf ~/dr/lib/darkradiant/modules/ -W -C -s | grep "vtable for RGBA" (08-26 19:55)
 35194: 0000000001a86ad0 88 OBJECT WEAK DEFAULT 21 vtable for RGBAImage
117323: 0000000001a86ad0 88 OBJECT WEAK DEFAULT 21 vtable for RGBAImage
[greebo@FLAXN:~]$ readelf -s -C -W /usr/lib/ | grep "vtable for RGBAImage" (08-26 19:55)
  2403: 00000000002101d8 32 OBJECT GLOBAL DEFAULT 18 vtable for RGBAImage

I'll try moving DarkRadiant's RGBAImage class into a namespace to see if that resolves the problem.

Yes, that fixed the problem. After moving RGBAImage to namespace image the textures are loading fine.
