Dear maintainer:

During a rebuild of all packages in unstable, this package failed to build.

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/202610/

Note: This happens because the configure "check for OpenMP support" requires
at least four CPUs to work, which is overkill. I found a way to fix that
and will make a team upload to fix it.


About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you cannot reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:mrtrix3, so that this is still
visible in the BTS web page for this package.

Thanks.
   Unable to configure OpenMP

  See the file 'configure.log' for details. If this doesn't help and you need
  further assistance, please post on the MRtrix3 community forum
  (http://community.mrtrix.org/), and make sure to include the full contents of
  the 'configure.log' file.

This time it may or may not work, but hopefully it will not fail in
the first 5 minutes as it happened the last time.
