I assume that http://sourceforge.net/p/libdwarf/code/ci/2192c62b5c54a432010ed358bf8147657587463c/ is the fix for this?
For the record, and given that even the CVE request doesn't actually tell you how to reproduce this, the answer is to run:
valgrind dwarfdump -F awbug5.elf
Where awbug5.elf is the file from the CVE request at http://seclists.org/oss-sec/2016/q1/135.
Still seems to be an issue in the latest upstream code so have reported it upstream.
