Hi,

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

Relevant part (hopefully):

The full build log is available from:
   http://aws-logs.debian.net/2016/11/11/scilab-ann_0.4.2.4-1_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.
