"OK" : "FAIL","\n";' FAIL $ PERL_UNICODE=63 perl -e '$_="ABDCEFGHIJK"; study; print /HIJK/ ? "OK" : "FAIL","\n";' OK This was in the 'en_US.UTF-8' locale. If I make utf-8 support conditional on locale, the problem goes away for the C locale: $ echo 'ABDCEFGHIJK' | PERL_UNICODE=127 LC_ALL=C perl -e '$_=<>; study; print /HIJK/ ? "OK" : "FAIL","\n";' OK Version-Release number of selected component (if applicable): ALL perl versions How reproducible: 100% Additional Information: This is upstream perl bug 37646 ( http://rt.perl.org/rt3/index.html?q=37646 ) -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
