Currently you cannot run monodoc (or other gtk-sharp applications) on CVS
HEAD on Linux PPC.

It is failing in handle_thunk after mono_delegate_to_ftnptr.

I retested this on SVN today and got some more information;

Some delegate marshalling will work (ie; mono gnome-hello-world.exe
will launch; but crash with the same thunking error on exit);

The place the failure is happening is:

search_thunk_slot:
if (!((is_call_imm (thunks) && is_call_imm (endthunks)) ||
(is_call_imm (difflow) && is_call_imm (diffhigh)))) {

for the crashing delegates its always falling into here; the reason is
difflow and diffhigh are obscenely large values (pdata->code is the
culprit)

I checked the ip getting set in the mono_add_patch_info and the
culprit isn't there; so it must be the guint8* code in
mono_arch_patch_code getting set incorrectly??

As a further update; 

I wiped ubuntu-ppc and tried fc3-ppc thinking it might be a ubuntu /
my installation problem.

This problem exists on fc3-ppc as well (mono-1.1.3/gtk# 1.0.4 and gtk#
HEAD)

For the sake of completeness; I tested this on 1.0.x; and it works
fine so this is just a bug on the 1.1.x branch
