[Bug mi/10041] New: Orphaned MI output when doing core-file debugging with -c option

["marc dot khouzam at ericsson dot com" <sourceware-bugzilla at sourceware dot org>]

In HEAD and 6.8 (didn't try earlier), when using the -c option

on the command-line to specify the core file, when in MI mode,

there is a 'orphaned' frame output that is output on the first

MI command. In the session below you can see that my first

command is "-gdb-set confirm" and it has a frame as part

of its output.  I ran the same command right after and got

the proper output.



> gdb -i mi -c core.32141 a.out
