Broken: version: 3.3.0 Alpha, branch: master, hash: 865cdff426

Short description of error
Null-pointer dereference when opening the Ellie Pose Library demo file. Probably caused by 0f7da9a72f.

The error appears in GPUCodegen::generate_resource, where info.name_buffer is accessed for appending, but it's null.
