Hmm!  No.  And I hadn't noticed it, thanks for pointing it out.

What's happening is, to do the ALLOBJ version, I use the 
section table in the objfile struct rather than the section
list in the bfd.  I do that because I want the relocated 
addresses of the shared libraries, not the raw addresses
that are in the bfd section table.  What I did not notice 
is that the .stabs sections are (apparently) omitted from
the objfile section table.  I suppose it's likely that the
dwarf debugging sections are too.

Well, fortunately I did not change the behavior of the 
original form of the command.  I'll mull this over, and
if I can think of a way to bring the new form into 
compliance, I will.  Otherwise we may just have to 
document the short-coming.
