I can't reproduce your problem with a trivial class with a static member
function like this:
class C {
public:
static int foo () __attribute__ ((section ("fred")));
};
Is there perhaps some inlining going on?
If you have a test case you can send me, I'll try to do better than just
grasping at straws like this. :-)

Yes indeed, that's an inter-section call to the "misc" section.

I fixed a bug in libnoexcept.a on 2001-10-16; previously overrides for
operator new[] were missing, and exception and rtti support could be
pulled in if you used those operators. You should have this fix with
your December CVS build, but it's worth checking (look for vnew.o and
vnewnt.o in libnoexcept.a). There's a fixed copy of the library at
http://prc-tools.sourceforge.net/misc/
Otherwise, nothing leaps to mind from this distance.
