[Bug 1100359] Re: Reading from <STDIN> results in "Interrupted system call" error when SIGCHLD handler is active

[Dmitry]

Hi again,

With help from Dave Mitchell I've found out that this bug has been
already fixed by the following commit:
http://perl5.git.perl.org/perl.git/commitdiff/be48bbe8d671b6841c3ec7cb734b98071afe3cd9

I have applied the patch and rebuilt the source package from Ubuntu
12.04 and I can confirm that it solves the problem.

The same bug has been reported and fixed in Fedora more than a year ago:
https://bugzilla.redhat.com/show_bug.cgi?id=767931

I hope it will be added in Ubuntu and Debian soon.

Title:
  Reading from <STDIN> results in "Interrupted system call" error when
  SIGCHLD handler is active

Status in “perl” package in Ubuntu:
  New

Bug description:
  Hi all,

  I've stumbled upon quite a strange behaviour on a server which has
  recently been upgraded from Debian squeeze to Ubuntu 12.04. I've
  narrowed it down to a simple test case which is attached.

  To reproduce the problem run "./f.pl | ./2.pl". Within a second
  (sometimes it takes a bit longer) it gives me the following:

  error: Interrupted system call at ./2.pl line 8, <STDIN> line 11.

  I've also tried it on 12.10 and got exactly the same behaviour.

  Best regards,
