[Openmcl-devel] Recent CHUD?

CHUD 4.6.0 seems to have quietly dropped support for ".spatch" files,
which had been the mechanism used to tell Shark the names of what
would otherwise be anonymous memory regions.  (Like lisp functions.)
It added support for "dSYM" files (which, if I understand correctly,
contain DWARF2 debugging info.)

I haven't installed the final XCode 3.1 yet, but in the beta versions
it worked to revert to 4.5.0 after installing XCode 3.1bwhatever.
("Worked" in this case means "worked with the CCL interface"; if
there's some sort of XCode/CHUD integration that depends on new
stuff in 4.6, I wouldn't know.)

4.5.0 is available as a free download from the ADC members site
(connect.apple.com; you need to register but don't need to pay.)

In the long term, some combination of trying to get the CHUD
developers to reinstate "spatch" file support and some exploration of
the alternatives (dSYM, whatever) seems like the right thing.  In
the short term, reinstalling 4.5 seems to work (as noted above.)
