[Resending, as my first try on March 1st apparently got lost somewhere. Apologies if this ends up as a duplicate.]
1. Problem Description: We're switching to Perl 5.10 in Debian soon, and I'm trying to update the mod_perl2 package to keep it working. Unfortunately the ModPerl-Registry test suite is failing on the Sparc architecture because apache2 is killed by a bus error (SIGBUS). I can reproduce this with a "clean" current SVN trunk (r631932) without any Debian-specific changes, and bisecting shows it broke with r620440. This is still with Perl 5.8.8 (from Debian unstable, package version 5.8.8-12). The kernel messages show the SIGBUS is an unaligned access (as usual on Sparc). I assume the U32->U16 changes in r615751 are related. Kernel unaligned access at TPC[45dc4c] handle_futex_death+0x20/0x90 This is Debian bug #468327, http://bugs.debian.org/468327 . I'm Cc'ing the report as [EMAIL PROTECTED], please keep the Cc if possible. I'd be happy to help in any way I can, please let me know if you need more information or testing. ~/mod-perl2$ make -C ModPerl-Registry/ test make: Entering directory `/home/buildd/mod-perl2/ModPerl-Registry' /usr/bin/perl -I../blib/arch -I../blib/lib \ t/TEST -clean [warning] setting ulimit to allow core files ulimit -c unlimited; /usr/bin/perl /home/buildd/mod-perl2/ModPerl-Registry/t/TEST -clean APACHE_TEST_GROUP= APACHE_TEST_HTTPD= APACHE_TEST_PORT= APACHE_TEST_USER= APACHE_TEST_APXS= \ /usr/bin/perl -I../blib/arch -I../blib/lib \ t/TEST -bugreport -verbose=0 [warning] setting ulimit to allow core files ulimit -c unlimited; /usr/bin/perl /home/buildd/mod-perl2/ModPerl-Registry/t/TEST -bugreport -verbose=0 /usr/sbin/apache2 -d /home/buildd/mod-perl2/ModPerl-Registry/t -f /home/buildd/mod-perl2/ModPerl-Registry/t/conf/httpd.conf -D APACHE2 -D PERL_USEITHREADS using Apache/2.2.8 (worker MPM) waiting 180 seconds for server to start: .[ error] server has died with status 255 (please examine t/logs/error_log) [ error] oh crap, server dumped core [ error] for stacktrace, run: gdb /usr/sbin/apache2 -core /home/buildd/mod-perl2/ModPerl-Registry/core sh: line 1: 23645 Terminated /usr/bin/perl /home/buildd/mod-perl2/ModPerl-Registry/t/TEST -bugreport -verbose=0 make: *** [run_tests] Error 143 2.
