Description Dodji Seketeli 2014-11-25 05:17:54 EST 
In version 0.159, elfutils gained a better support for alternate debug information sections emitted by the debug information compression tool, dwz. 

This is critical to develop tools that use elfutils to read the compressed debug information.

The particular piece of improvement that is interesting to have is summarized in the NEWS file of elfutils for the 0.159 version:

libdw: Support for DWZ multifile forms DW_FORM_GNU_ref_alt and
       DW_FORM_GNU_strp_alt is now enabled by default and no longer
       experimental. Added new functions dwarf_getalt and dwarf_setalt
       to get or set the alternative debug file used for the alt FORMs.

One practical example of issue the missing functionality of the current 0.158 version of RHEL 6.6 causes is this problem reported in the bug tracker of the libabigail project: https://sourceware.org/bugzilla/show_bug.cgi?id=17193#c5
