`ipcalc 61.177.0.0 - 61.177.255.255` should give 61.177.0.0/16 but it
runs endless now until I hit ctrl-c. I remember, that worked in the
past...

There was no ipcalc update in the last time but there was a perl update
to 5.34.

I was able to fix that bug by taking Math::BigInt and Math::BigFloat
from perl 5.36. They work seamless.

I will reassign the bug to perl-modules.

retitle 1012704 libmath-bigint-perl: busy loop with bignum bitwise operations
severity 1012704 serious
reassign 1012704 libmath-bigint-perl 1.999835-1
found 1012704 1.999837-1
tag 1012704 upstream
thanks

Thanks for the report.

This boils down to

  % perl -Mbignum -e '1 | (1 >> 1)'
  Deep recursion on subroutine "Math::BigInt::bior" at /usr/share/perl5/Math/BigFloat.pm line 3883.
  Deep recursion on subroutine "Math::BigFloat::bior" at /usr/share/perl5/Math/BigInt.pm line 3513.

Also happens with other bitwise operations like & and ^ .

The bug is not specific to any Perl versions but seems to be fully
contained in Math::BigInt / Math::BigFloat.  The versions of those
modules that ship with Perl 5.34.0 (Math::BigInt 1.999818) and Perl
5.36.0 (Math::BigInt 1.999830) are not affected by the bug, but you
have the newer separate libmath-bigint-perl package installed where the
bug triggers.

It seems to have regressed upstream around 1.999832 (where it started
to spit errors) and 1.999834 (where the errors became infinite recursion.)
The first version in Debian that had the bug was 1.999835-1, which
fits your upgrade timeline.

So I'm reassigning this once more. Also raising the severity as this looks
rather Bad.

Would be great if (other) pkg-perl maintainers can pick this up from
here and forward upstream etc. Otherwise I'll get to it eventually :)

From:

To:

versions of Math::BigInt available in bookworm at the moment:
- 1.999830 in perl-modules-5.36
- 1.999837 in libmath-bigint-perl

Since 1.999837 breaks at least ipcalc, it may be better to remove
libmath-bigint-perl 1.999837 from bookworm than releasing with a
broken version.

Since this means a fallback to 1.999830 from perl-modules-5.36, this
should not be an issue.

Greetings
Roland
