I can't speak to the gcc9 part, but this would probably have failed on aarch64 and s390x as well, you just didn't notice because those aren't arches in copr. C's "char" type is either signed or unsigned by default, it's a function of the processor-specific ABI. It happens to be signed on i686 and x86_64, and unsigned on all the other arches Fedora supports. So: > /builddir/build/BUILD/gdcm-2.8.8/Testing/Source/Common/Cxx/TestString2.cxx:29:24: > error: narrowing conversion of '-1' from 'int' to 'char' [-Wnarrowing] This would only trigger on unsigned-char arches, because you can't represent -1 with an unsigned number. - ajax _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
