The test-fork1 failure is still unexplained and happens intermittently.

I have built a lot of unstable on my rp3440. I think this one causes failures in the thread testsuites of perl, python2.7 and glib2.0. These are characterized by tests hanging.

There is another class of failures. They typically cause my rp3440 to crash due to cache corruption. The GCC libgomp and libatomic-ops testsuite seem to trigger
this one.  As I have mentioned, it's the libgomp "for" tests that

The cancellation issues happen in tst-cancel*.

I believe the cancellation issues are toolchain issues and I need to
look into them.
Possibly, this is related to the following bug that I found last week building mpfr-3.1.0:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50691
A call to __tls_get_addr clobbers first argument of call to mpfr_cache. Don't have a
fix at the moment, but there is a simple testcase.

On a different subject, I tried to get udev-172-1 working. However, this breaks bootstrap due to an invalid argument in a call to inotify_init. It's somewhat timing dependent since some kernels will boot if they build enough of /dev before udev messes up. In any case, I believe that Guy Martin posted a patch a year or so ago to correct an inconsistency between the glibc and the kernel for some bit definitions. I'm thinking this may fix the
udev problem.

It appears that this change got lost and didn't make it into the debian glibc patch set.
Was a consensus reached on how to fix this inconsistency?

I plan on seeing if I can resolve the GCC mpfr bug, then I want to rebuild glibc with
the flag bits fixed.

I also found a GCC ICE compiling udev-172-1 with gcc-4.4. Gcc-4.5 and gcc-4.6 seem
ok.
