Description Sinny Kumari 2016-02-26 13:14:39 UTC 
Description of problem:
Test misc_test fails on ppc64 BE with following error message:

misc_test.....
RPM build errors:
Algorithm failed test vectors. (5)
misc_test.c:18:crc32_test()
error: Bad exit status from /var/tmp/rpm-tmp.xYmIrH (%check)
    Bad exit status from /var/tmp/rpm-tmp.xYmIrH (%check)

Complete build log is available at http://ppc.koji.fedoraproject.org/kojifiles/work/tasks/2547/3172547/build.log from koji build http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=3172546

Version-Release number of selected component (if applicable): libtomcrypt-1.17-28.fc24

Additional info:
Failure happens only when following section in test file testprof/misc_test.c runs :

#ifdef LTC_CRC32
   DO(crc32_test());
#endif

If we comment this section, remaining tests and build pass successfully.
Comment 1 Dan Horák 2016-03-01 14:51:07 UTC 
The lib overrides the distro-wide -O2 into -O3, but even going down to -O0 did not help, same no change with -fno-strict-aliasing or -mno-lra (as the usual tricks), we are still investigating.
Comment 2 Rafael Fonseca 2016-03-03 15:16:27 UTC 
There is a chance it's a bug in the code. I reported it upstream [1].

Comment 3 Dan Horák 2016-03-03 17:37:06 UTC 
And same problem on s390x, so it's likely big endian problem. I haven't expected a rebase under the same version ...
Comment 4 Than Ngo 2016-03-09 15:47:22 UTC 
i created a fix for this issue and send the patch to upstream. It built fine with the fix.
