> Um, I'm not sure what is happening.  My GNU/Linux amd64 box appears to pass both times:

I've found the right machine (YelloDog 3.0), the attached appears to 
work on both yellow dog and IRIX (and Fedora Core).

The new patch modifies find_pc_partial_function supply the PC's section 
when available.

Look ok?

The problem was that the symbol lookup was finding a symbol from a 
previous section, instead of no symbol in the current section.  That 
leads to this test (using Joe's rewrite):

not triggering.  ->stop_func_name had a non-NULL but bogus symbol name.

ok?

PS: I think GDB has a few too many symbol lookup interfaces :-(
