I have checked in an alternative patch to fix this BZ.
The problem is that the patch for PR 18879 does not work with the RHEL 6.9
binutils sources, since this version of readelf does not actually have the
capability to dump unwind information. In theory this should mean that the
bug fixed in PR 18879 is never encountered and so no patch is needed. In
practice however it turns out that the test case for PR 18879 triggers a
*different* bug in the 6.9 binutils, and so a patch is needed after all.
Verified with build binutils-220.127.116.11.2-5.46.el6.
Since the problem described in this bug report should be
