Hi,

During a rebuild of all packages in stretch (in a stretch chroot, not a
sid chroot), your package failed to build on i386.

The full build log is available from:
   
http://aws-logs.debian.net/2017/04/18/ruby-rspec_3.5.0c3e0m0s0-1_testing-i386.log

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.

Hi,

I did the archive rebuild that resulted in this bug on a machine with a
jessie kernel. I did another rebuild on a machine with a stretch
kernel, and this failure disappeared.

My best guess is that this has something to do with a stack overflow,
in a way similar to #750593 (see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=750593#157 and #797530
(fixed in stretch, not jessie).

Given that this doesn't affect building on a machine with a stretch
kernel, I'm closing the bug.

Lucas
