mi-break.exp regresses when tested with MI running on a secondary UI, with RUNTESTFLAGS="FORCE_SEPARATE_MI_TTY=1". The problem is simply that the test sets a breakpoint, and attaches "print" commands to the breakpoint. Since breakpoint commands always run with the main UI as current UI, the breakpoint command's output goes to the main UI. So we need to tweak the test to expect it there. gdb/testsuite/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * gdb.mi/mi-break.exp (test_breakpoint_commands): Always expect breakpoint command's output on the main UI. (test_break): New procedure, factored out from calls in the top level. (top level): Use foreach_with_prefix to test MI as main UI and as separate UI.
