Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

Relevant part (hopefully):
http://aws-logs.debian.net/2016/11/11/libsys-cpuaffinity-perl_1.10-1_unstable.log

This failure happens on a CPU with TSX extensions available, but is not
reproducible on a machine without them. For context, I recommend reading the
thread starting at https://lists.debian.org/debian-devel/2016/11/msg00210.html

The node used is an Amazon EC2 VM with 64 cores. /proc/cpuinfo says:
   model    : 79
   model name : Intel(R) Xeon(R) CPU E5-2686 v4 @ 2.30GHz
   stepping : 1

A list of current common problems and possible solutions is available at
http://wiki.debian.org/qa.debian.org/FTBFS . You're welcome to contribute!

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.

We believe that the bug you reported is fixed in the latest version of
libsys-cpuaffinity-perl, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 844141@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.

reopen -1
severity -1 important

This might have been a bit premature, Lucas can still reproduce the
problem in his setup; cf.
https://rt.cpan.org/Ticket/Display.html?id=118730

So reopening but setting the severity to important as this only
appears in a rare corner case now.


Cheers,
gregor
