Fix bug in ArchSpec::MergeFrom

Authored by clayborg on May 7 2019, 2:57 PM.



Previous ArchSpec tests didn't catch this bug since we never tested just the OS being out of date. Fixed the bug and covered this with a test that would catch this.

This was found when trying to load a core file where the core file was an ELF file with just the e_machine for architeture and where the ELF header had no OS set in the OSABI field of the e_ident. It wasn't merging the architecture with the target architecture correctly.

Ah, this was my bad. Thanks for taking care of this.


I think it might be a good idea to assert A's values here to show that nothing changed except the OS after the MergeFrom call.
