The problem seems to come from changes in exception handling between
3.2 and 3.3. If I specify -fno-exceptions the compile time regression
between 3.2 and 3.3 reduces to 8.6s vs. 10s total time, without
-fno-exceptions it is 10s vs. 146s (otherwise just -O2). The same
testcase compiled with -fno-exceptions (libstdc++ stuff differs and
is incompatible) can be fetched at
http://www.tat.physik.uni-tuebingen.de/~rguenth/DynamicLayout.cmpl.ii.noex.gz
I'm now trying to collect profiles for both cases
Richard.

I have tried to compile the test case with a profiling 3.3 (mainline
rejects the code). It didn't quite work...
The profiling information makes it all even slower, and it hogs up
so much memory that the compiler just dies. My profiling compiler
dies after 15 minutes or so. The final announcement is:
int GridPartition<Dim>::partition(const D&,
std::vector<Node<Interval<Dim>, Interval<Dim> >*,
std::allocator<Node<Interval<Dim>, Interval<Dim> >*> >&, const
ContextMapper<Dim>&) const [with D = Interval<1>, int Dim = 1] GC
{197832k -> 53003k}Killed
(box is i586-pc-linux-gnu with 192MB RAM, and >300MB swap)
I don't know what exactly to make of this, but obviously eating so
much memory is *not* good. Also, the biggest contributions to the
compile time apart from expand are cfg-cleanup and jump, so
apparently expand fills memory with lots of garbage left to be
cleaned up by cfg-cleanup and jump. Which is not really news, of
course.
