Reported upstream: https://github.com/randombit/botan/issues/882
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.
Did some testing with (GCC) 7.0.1 20170309 (Red Hat 7.0.1-0.12): It seems that switching on -ftree-slp-vectorize together with -fpeel-loops (in addition to what is in -O2) creates code that fails the testsuite. Could be a GCC issue.
