--- Comment #16 from Milian Wolff <mail@milianw.de> ---
ok, more information:

this is actually *not* a deadlock, but our code scales very badly (I'll have to
investigate why) with the template recursion depth. If you add debug output of
the depth_counter (DelayedTypeResolver::exchange in templatedeclaration.cpp),
you'll notice that it gets quickly up to say ~15 but then gets slower and
slower, until it reaches (on my machine) about 21 where it takes like a minute
already.

So, as a workaround I consider reducing the allowed template recursion depth to
20. Anyone opposed?
