While the full fix for PR 15180 isn't in, it's best if we at least make sure that GDB doesn't lose control when a breakpoint is set at the same address as a dprintf. gdb/ 2014-06-02 Pedro Alves <palves@redhat.com> * breakpoint.c (build_target_command_list): Don't build a command list if we have any duplicate location that isn't a dprintf. gdb/testsuite/ 2014-06-02 Pedro Alves <palves@redhat.com> * gdb.base/dprintf-bp-same-addr.c: New file. * gdb.base/dprintf-bp-same-addr.exp: New file.
