Description Jan Kratochvil 2014-01-15 12:54:18 UTC 
Description of problem:
elfutils does not read symbols as:
 * dwfl_link_map_report() does not find DT_DEBUG so r_debug_info is left empty
 * dwfl_segment_report_module() reports only the LOAD segment size so .symtab is stripped out

Version-Release number of selected component (if applicable):
GIT HEAD: e1b6b9d3131f32ef54932388c814adc02ca6a329

How reproducible:
Always.

Steps to Reproduce:
src/stack -e testfile-backtrace-demangle --core testfile-backtrace-demangle.core -lm

Actual results:

This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle.
Changing version to '22'.

Comment 4 Fedora End Of Life 2016-07-19 10:53:01 UTC 
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
Comment 5 Mark Wielaard 2016-07-19 11:00:27 UTC 
This should have stayed open. Changing version to rawhide (it already has FutureFeature keyword) hopefully that helps.
