Dom, Unfortunately I have to call your attention to 2 smoke-test failures in ext/POSIX/t/mb.t which were recorded *after* I applied your patch. http://perl5.test-smoke.org/report/89146 logs at: http://perl5.test-smoke.org/logfile/89146 http://perl5.test-smoke.org/report/89211 logs at: http://perl5.test-smoke.org/logfile/89211 (These can be tracked via this search: http://perl5.test-smoke.org/submatrix?test=../ext/POSIX/t/mb.t&pversion=5.31.1) In each case the failures in mb.t occurred when blead was configured as follows: [stdio] -Dcc=clang -Accflags="-Werror=declaration-after-statement -g -fno-omit-frame-pointer -fsanitize=address -fno-common -fsanitize-blacklist=`pwd`/asan_ignore" -Aldflags="-fsanitize=address" With and without -DDEBUGGING. A couple of points: 1. Tester is using what I would guess is an advanced version of the Linux kernel: 5.0.9-200 versus my own 4.15.0-51 (Ubuntu 18.04 LTS). OTOH, we are getting smoke-test reports from rigs with even higher-numbered Linux kernels. 2. I myself don't understand all those compiler switches the tester is using. In particular, 'make' fails for me on FreeBSD-11.2 when I use those compiler switches. 3. Nonetheless, when I build a perl with all those switches (except -DDEBUGGING), I get those test same failures. See attachments. 4. When I build blead with those same compiler switches at the commit immediately prior to the one where I applied your patch, I get a PASS. ##### $ git show | head -1 commit fb55ce6b7596b9e94f941cf83eac5ff84f760ea2 $ cd t;./perl harness -v ../ext/POSIX/t/mb.t; cd - ok 1 - mblen() basically works ok 2 - MB_CUR_MAX is at least 4 in a UTF-8 locale ok 3 - mblen() recognizes invalid multibyte characters ok 4 - mblen() works on UTF-8 characters ok All tests successful. Files=1, Tests=4, 0 wallclock secs ( 0.02 usr 0.00 sys + 0.26 cusr 0.12 csys = 0.40 CPU) Result: PASS ##### So your patch has triggered test failures, albeit under these very obscure conditions. I'm going to revert your patch from blead and then re-apply it in a branch so that we can continue to gather smoke-test reports. Thank you very much. -- James E Keenan (jkeenan@cpan.org) --- via perlbug: queue: perl5 status: open https://rt.perl.org/Ticket/Display.html?id=134182Thread Previous | Thread Next
