It certainly looks that way. The ar format is not ideal to rewrite in place, which is why it is unpacked and repacked like this. Which isn't super efficient, but somewhat surprising it takes 20+ hours... That must be a pretty big .a file. We'll see if we can come up with some trick to make this more efficient. For now as workaround please add: %undefine _preserve_static_debuginfo to the spec file for now.
