One question: on line 94 of the patch, is it necessary to call gdb_bfd_ref on `result`? In this case, bfd_mach_o_fat_extract was basically a noop, and `abfd` was already reference counted by solib_bfd_open. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
