How often have you tried to build the package? Were noatime-mounts
used? If you only built it once or used noatime mounts, this could be
a duplicate of one of those two bug reports:

  https://bugs.debian.org/760061 (Ok, the gcc-5 issue doesn't look like hanging.)
  https://bugs.debian.org/764650 (test suite failures, too, but elsewhere)

Thanks.

... because they don't show the cause.

Here's the failed test:

Test successful.
Running test:  Nested TRAPEXIT

Thanks for these explicit instructions. Will try that.

Don't seem to be any of them on a first glance.
