From mec.gnu@mindspring.com

This is my first perl bug report\, so be gentle.

I can't run perlbug on the system where the build fail occurred because that system doesn't allow outgoing mail. And besides\, I think the information that perlbug collects would not be helpful for a build failure.

This is a build failure on ia64-unknown-linux-gnu running debian woody. I am building perl 5.8.4 with gcc 3.3.4 (stock gcc 3.3.4 from ftp.gnu.org\, which I built myself with binutils 2.15).

I configured with​:

  sh /house/chastain/source/perl-5.8.4/Configure -Dmksymlinks -Dprefix=/tmp/chastain/install/ia64-unknown-linux-gnu/debian-woody/host/perl-5.8.4 -Uinstallusrbinperl -d -e

The end of build.log says​:

  cc -L/usr/local/lib -o miniperl \   miniperlmain.o opmini.o libperl.a -lnsl -ldl -lm -lcrypt -lutil -lc   ./miniperl -w -Ilib -MExporter -e '\<?>' || make minitest   Attempt to free unreferenced scalar​: SV 0x600000000002cb40.   make​: [extra.pods] Error 1 (ignored)   ./miniperl -Ilib configpm configpm.tmp   make​: *** [lib/Config.pm] Segmentation fault

I hit google and found some random hint that this might be a problem with the gcc optimizer. So I changed my configuration line to​:

  sh /house/chastain/source/perl-5.8.4/Configure -Dmksymlinks -Dprefix=/tmp/chastain/install/ia64-unknown-linux-gnu/debian-woody/host/perl-5.8.4 -Uinstallusrbinperl -Doptimize=none -d -e

With optimize=none\, perl 5.8.4 builds and installs and 'make test' says ...

  All tests successful.   u=4.97852 s=0.722656 cu=296.415 cs=11.7598 scripts=806 tests=80069

It's likely this is a known bug but I just wanted to contribute my data points.

We have Perl version 5.6.1 running ia64-linux\, we need to either upgrade or install Perl version 5.8.5 on our system. During running the make command after submitting the command "sh Configure -de"\, the system generated the following message​:

Can someone help us to re-build the Perl-5.8.5? Thx.

Here is the "uname -a" from our system​: uname -a Linux halowtier1 2.4.20-telco-1.24.2-mckinley-smp #1 SMP Thu Apr 29 13​:56​:12 MDT 2004 ia64 unknown

I will provide the core file if need it.

Your helps are appreciated. Thx.

I just tried perl-5.8.7 and I still get the same failure​: ./miniperl -Ilib configpm --heavy=lib/Config_heavy.pl configpm.tmp Attempt to free unreferenced scalar​: SV 0x6000000000018ee0 at configpm line 2.

It builds OK on HPUX ia64 but on redhat AS 3 ia64 it started to fail at perl 5.8.4. Any suggestions?

Just to advice you about a problem with IA64 gcc-3.2.3-47 and perl-5.8.7\, that seems to be well known\, but not mentionened in your README's.

The problem shows during compilation as​: ./miniperl -Ilib lib/lib_pm.PL Attempt to free unreferenced scalar​: SV 0x6000000000034d00 at lib/lib_pm.PL line 1. Attempt to free unreferenced scalar​: SV 0x600000000003c7c0 at lib/File/Basename.pm line 138. Attempt to free unreferenced scalar​: SV 0x600000000003c7c0 at lib/File/Basename.pm line 142. Attempt to free unreferenced scalar​: SV 0x6000000000065680 at lib/warnings.pm line 134. Attempt to free unreferenced scalar​: SV 0x600000000003c7f0 at lib/File/Basename.pm line 143. Attempt to free unreferenced scalar​: SV 0x6000000000042980 at lib/Exporter/Heavy.pm line 3. make​: *** [lib/lib.pm] Segmentation fault

The workarounds are​: 1. Upgrade gcc to gcc-3.2.3-50 or later 2. Compile pp_ctl.c\, pp_hot.c and pp_sort.c using -O1 3. Compile pp_ctl.c\, pp_hot.c and pp_sort.c using -O2 and -fno-delete-null-pointer-checks

I have tried workaround 3 on both 5.8.6 and 5.8.7 and it works fine.

Maybe you should consider er README.ia64 with this information?

An existing chang to the hints/linux.sh was made to fix this problem with PPC chips. It defaults optimize to -O1 on all PPC/Linux. I'd prefer to simply add the "-fno-delete-null-pointer-checks" to ccflags. Any other thoughts?

It is OK with me\, the customer I helped with this problem has tested perl compiled with "-fno-delete-null-pointer"and it works without giving him any problems. But I think if possible it should only be done for versions of gcc versions less than gcc-3.2.3-50

Only problem is that "less than gcc-3.2.3-50" has a different meaning for RedHat\, Suse\, Ubuntu\, Slackware\, etc. Also\, cruising through the RedHat bugzilla suggest that this problem exists for the 3.2\, 3.3\, and 3.4 branches of the gcc tree\, without a good answer of where this problem is actually solved. So\, I've added the following patch to hopefully deal with this problem.

Change 28155 by stevep@​stevep-kirk on 2006/05/10 23​:02​:20

  Add -fno-delete-null-pointer-checks to ccflags on Itaniums when   compiling with gcc's 3.2\, 3.3\, or 3.4. This fixes RT #37156.
