Segfault in UI_icon_draw_cache_end on startup; fresh new build. Fresh new developer;)

I’m trying to dabble a bit in blender development; It crashed on startup after command-line build. Is this a known issue?

I can’t really tell without exact steps of how you did your build but and I’m not really fluent in macs but: Master is not always stable. Crashes on startup are rare, but they do happen.

You can try to first checkout a known working version, for example;

git checkout v2.90.0

(git tag to list available tags)

And build that. If that also crashes, you can be sure something wrong in your build setup.

That did it! I’m unblocked.

So I guess that’s something for your mac maintainer to look into.

Thanks for the help!

You can try to checkout master again in a few days and see it it’s fixed. There are lot’s of people using macs, so I can’t imagine it being broken for long.

I don’t get a crash on intel HD 6000, macOS Mojave. Same commit as yours.
If this also happens in the build created by make lite (or
cmake -C ../blender/build_files/cmake/config/blender_lite.cmake ../blender
), then you may want to do a git bisect to find the problematic commit.
Also try changing the GPU.

side note, icon_draw_cache_texture_flush_ex is in my suppression file for leak sanitiser.
