Hi,

this bug tracks progress with regards to occassional FTBFS (about 5-10%
of all buildd builds across different architectures) due to a hanging
test suite. They're difficult to reproduce outside the buildds, even
with pbuilder. I ran the test suite 200 times in a row inside a
non-interactive pbuilder session and was not able to trigger the issue.

tracker):

Builds where later builds succeeded again, either giveback or another
upload:

There's a small possibility that former test suite hangs on hurd-i386
are a similar issue. But they happened so often, that we completely
disabled the test suite on hurd-i386 for now, as it's no release
architecture:

The recent (but workarounded) FTBFS on s390x
(https://buildd.debian.org/status/logs.php?pkg=zsh&arch=s390x) are a
different issue and are tracked in this gcc-4.9 bug report:
