            Bug ID: 21541
           Summary: eu-readelf --notes fails to dump PRSTATUS data?
           Product: elfutils
           Version: unspecified
            Status: UNCONFIRMED

The core file mentioned

Version: latest master
         I built elfutils with --prefix with a non-default path.
         Native build on x64.

Problem: Run eu-readelf --notes core.dump
         The core-dump is generated from a x64 program.
         A. The one I built cannot dump details PRSTATUS data.
         B. On another machine, distribution shipped elfutils-0.158 dumps 
            details of PRSTATUS data for the same core-dump.

I have no glue where it is wrong. (Or the core file is broken?)
There seems to be no relevant configure options.
At runtime eu-readelf doesn't tell why it does not dump details of PRSTATUS.

config report:
        elfutils: 0.169 (eu_version: 169)

    Prefix                             : /home/xxx/ins
