I think I am getting the same thing (only on OSX - does not happen on Windows for instance).

The crash happens just after opening an old scene with the old hair system (no manipulation, no render involved). It is wireframe openGL related, and appeared maybe 2 days ago (I compile every day from source, in branch master).

Here is the error I get:

ERROR (gpu.shader): hair_refine_shader_transform_feedback_workaround_create FragShader:

61 | fragColor = finalColor;

    | 
    | gpu_shader_3D_smooth_color_frag.glsl:12:0: Error: Use of undeclared identifier 'fragColor'
    | gpu_shader_3D_smooth_color_frag.glsl:12:0: Error: Use of undeclared identifier 'finalColor'
    |

62 | fragColor = blender_srgb_to_framebuffer_space(fragColor);

    | 
    | gpu_shader_3D_smooth_color_frag.glsl:13:0: Error: Use of undeclared identifier 'fragColor'
    | gpu_shader_3D_smooth_color_frag.glsl:13:0: Error: Use of undeclared identifier 'fragColor'

My workaround fix has been to edit source/blender/gpu/shaders/gpu_shader_3D_smooth_color_frag.glsl and re-introduce:

ifndef USE_GPU_SHADER_CREATE_INFO

in vec4 finalColor;
out vec4 fragColor;

endif

And obviously recompile.

Hopefully this is enough additional information to get going on a proper official fix.

This seems to have now (today May 4th) been properly addressed upstream, by Germano Cavalcante, through Fix #97835. (No need for my workaround temporary fix above).
