------------------ Additional Follow-up Comments ----------------------------
I've attached a patch that fixes the problem.  There still may be some underlaying 
cleanup needed.  (Check why the GSInvocationCallback functions get a selector with 
platform specific types and fix that).  But I'll leave that for later (or someone else 
to pickup) because I'm out of time now.  It would be nice if those of you who use DO 
intensively (maybe even cross platform DO) could take it for a spin.

Summary:  mframe vs. gcc/libobjc selector types

Original Submission:  We use the platform dependent mframe code to implement 
NSMethodSignature's method types while gcc/libobjc uses a platform independent 
encoding scheme (well in pre 3.4 version it wasn't fully platform independent as it 
marked where registers were used depending on the platform but the "ObjC improvements" 
merge broke that.)  Unfortunately we use these mframe signatures to register selectors 
for DO (see Testing/nsnotification).  Yet the mframe encoding "dialects" cannot be 
handled by libobjc which causes objc_error aborts on some platforms (e.g. linux/hppa 
but potentially others) when selectors are registered with those types.  I believe we 
need to reorganize NSMethodSignature to use the "gcc/libobjc" encoding dialect instead 
of the mframe dialects which should be resrced for DO processing.  I haven't looked 
into how this could be done yet.  Maybe someone a bit more familiar with this code may 
want to jump in and have a look at it.  Riccardo
Mottola can provide information (if I'm not available) and test.  Otherwise I'll drop 
it on my TODO list.
