--- Comment #9 from Petr Pisar  ---
I recommend removing this package from Fedora. Upstream has not responded to
bug reports for years and did not do any new release. This package seems be not
required by any other package in Fedora.

--- Comment #8 from Fedora End Of Life  ---
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '24'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 24 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

We have a similar bug on non-hardened ppc64le (bug #1393834). It looks like a
floating point arithmetic issue.

--- Comment #4 from Petr Pisar ppi...@redhat.com ---
If I only relink perl from the the same build directory as the affected comes
from with old ldflags:

$ gcc -o perl -fstack-protector-strong -L/usr/local/lib -Wl,--enable-new-dtags
perlmain.o  libperl.so `cat ext.libs` -lpthread -lresolv -lnsl -ldl -lm -lcrypt
-lutil -lc

And use the the perl to run the t/02bad_deriv.t, it passes. If I relink the
perl with the hardened ldflags:

$ gcc -o perl -Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld
-fstack-protector-strong -L/usr/local/lib -Wl,--enable-new-dtags -Wl,-z,relro
-specs=/usr/lib/rpm/redhat/redhat-hardened-ld perlmain.o  libperl.so `cat
ext.libs` -lpthread -lresolv -lnsl -ldl -lm -lcrypt -lutil -lc

the test fails.

Also the test passes with the hardened perl when running under valgrind.

--- Comment #5 from Petr Pisar ppi...@redhat.com ---
The minimal broken flags are:

$ gcc -o perl -pie  perlmain.o  libperl.so `cat ext.libs` -lpthread -lresolv
-lnsl -ldl -lm -lcrypt -lutil -lc

Removing the -pie option helps.

The difference is architecture: i686 passed, x86_64 failed.

--- Comment #1 from Petr Pisar ppi...@redhat.com ---
Comparing recent passing koschei build
https://apps.fedoraproject.org/koschei/package/perl-Algorithm-CurveFit/671405
and the failed scratch build
http://koji.fedoraproject.org/koji/taskinfo?taskID=10349864 does not divulge
any significant difference in the build root:

Removed packages:
libasan-5.1.1-4.fc23
libatomic-5.1.1-4.fc23
libcilkrts-5.1.1-4.fc23
libmpx-5.1.1-4.fc23
libubsan-5.1.1-4.fc23
Added packages:

I can reproduce the bug locally and installing the five packages does fix it.
