Probably just a bug/missing feature in elfutils. If the binary is
statically linked it might be that we are not able to find all
information we need. There have been other reports about that.
https://bugzilla.redhat.com/show_bug.cgi?id=1053583
Given that most binaries are not static it hasn't been a problem in
practice.

Could you post the binary somewhere?
Then I will take a look at what is going wrong.

Thanks,

Mark
