Description Florian Weimer 2018-01-30 13:51:35 UTC 
See bug 1515865 comment 9.

This is another wrong-code bug in -fstack-clash-protection on i686.  It causes miscompilation of pcre and pcre2.  Filing downstream for tracking purposes.  The upstream bug has a reproducer.
Comment 1 Jeff Law 2018-02-01 16:38:21 UTC 
Fixed upstream.  Builds spinning for f27 and rawhide.
Comment 2 Petr Pisar 2018-02-02 11:14:32 UTC 
Thanks. I confirm gcc-8.0.1-0.9.fc28 works for me.
