Created attachment 800574 [details] Suggested fix Description of problem: The prelinker causes several programs to crash on s390x. The problem is that an R_390_IRELATIVE relocation for a memcpy IPLT in libc gets added to the conflict list as a normal R_390_64 relocation. The IPLT then ends up calling the ifunc resolver rather than a real memcpy implementation. Version-Release number of selected component (if applicable): prelink-0.5.0-1.fc19.s390x Steps to Reproduce: From an un-prelinked state: $ sudo prelink /usr/bin/python $ python Segmentation fault (core dumped) $ sudo prelink -u /usr/bin/python $ python Python 2.7.5 (default, Aug 27 2013, 05:19:42) [GCC 4.8.1 20130603 (Red Hat 4.8.1-1)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> The attached patch fixes things for me.
Looks correct, committed as r207 to prelink SVN. Will try to add a testcase tomorrow.
I've also committed s390 and s390x additions to testsuite/ifunc.h, with r207 reverted all the ifunc* tests FAIL on s390x, with r207 they all pass.
There was a similar bug to this in s390 31-bit support, committed as r209.

Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
