Ah...interesting.  For the main object, the symtab points to
c:\some_dir\main.c and the symtab->next points to just main.c.  It's the
main.c that gets caught and returned.  In the solib, we only see the
c:\some_lib\display.c so the FILENAME_CMP fails..

So you are correct, lookup_partial_symtab is failing.
