glfw Opengl4 demo Segmentation fault

[kotvkvante]

1. I'm trying to run glfw3 opengl4 demo example.

make
rm -f bin/demo 
cc main.c -std=c89 -Wall -Wextra -pedantic -O2 -o bin/demo -L/usr/local/lib -lglfw3 -lGL -lm -lGLU -lGLEW

Everything compiles fine.

but then:

./bin/demo 
Segmentation fault (core dumped)

I see a black window and then it closes.
2) OpenGL 3, OpenGL 2 and Sdl examples works fine.

3. I'm trying to use gdb to find out where program fails:

cc main.c -ggdb -std=c89 -Wall -Wextra -pedantic -O2 -o bin/demo -L/usr/local/lib -lglfw3 -lGL -lm -lGLU -lGLEW
gdb bin/demo
run

Output:

I think this is because of GL_ARB_bindless_texture functionality. Without this option example works fine.
Does this bug occurs because of my amd drivers?

I can't find list of supported opengl functions for my drivers..

Related: #190 - sounds like the same or similar case.

I am no expert on OpenGL so I would need to spend some more time educating myself about the details. Currently I am out of time, but perhaps someone more knowledgeable will chime in 😉.

Probably a driver issue, doing the same on Linux (6.4.6) with an Nvidia card (RTX 2080), the program runs without any issue.

With Nvidia, there is nvidia-settings which gives detailed information about the device :

Isn't there a similar tool with AMD?

[satk0]

@riri glxinfo shows the GLX settings for AMD. GLX_ARB... and other functions are there. Although, I have the same problem as mentioned above.

I'm getting these errors:

Getting the same error, Manjaro Linux, GLFW 3.3, and glxinfo shows:

I've added -g to CFLAGS, this is my output:
