Hi,

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

Relevant part (hopefully):
http://aws-logs.debian.net/2017/04/18/gap-radiroot_2.7-2_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.

Hello Lucas,
Sorry for the delay, for some reason my ISP blocked this email.
Do you know how much memory is there on this system ?
The test suite need 128M which does not seems unreasonable.

I did a test build using cowbuilder for stretch i386 and it worked fine.
It seems to me your system was experiencing a memory crunch during the
build.

Cheers,
Bill.

256 GB of RAM on the amd64 host, of which only 4GB is available per
process since it's i386.

How many threads
getconf _NPROCESSORS_CONF
report ?

I think the problem is that it needs 128M by threads.

64, so yes, that's probably the issue

There is only 64MB of virtual memory by threads.
It is not a very realistic setup.
No real i386 box is going to have some much threads.

Honestly I do not really know how to fix this unless I hardcode
a limit for the number of threads in the test suite.

Cheers,
