            Bug ID: 19966
           Summary: [2.23 Regression] binaries linked with
                    --version-script segfault with 2.23 on
                    powerpc-linux-gnu
           Product: glibc
           Version: 2.23
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dynamic-link
          Assignee: unassigned at sourceware dot org
          Reporter: doko at debian dot org
  Target Milestone: ---

binaries linked with --version-script segfault with 2.23 on powerpc-linux-gnu. 
The binaries don't need to be built with 2.23, but just start segfaulting.

Several packages link their binaries, not just the shared libraries with
--version-script= ...
On Ubuntu 16.04, this is at least seen for xorriso (src:libisoburn), lua5.x and
llvm (when built using autoconf, not cmake).

Fedora report this for s390x too:

libburn and libisofs seem to be affected too.
