            Bug ID: 17471
           Summary: repeating a background command makes it foreground
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: palves at redhat dot com

Running a background command, and then pressing "enter" to repeat it repeats
the same command, but in the foreground.

This only happens if the command is passed some extra argument other than the
"&", such as "c 1&", "next 2&", "c -a&", etc.

Example:

(gdb) b foo
Breakpoint 2 at 0x4005d4: file bg-execution-repeat.c, line 23.
(gdb) c 1&
Not stopped at any breakpoint; argument ignored.
Continuing.
(gdb) 
Breakpoint 2, foo () at bg-execution-repeat.c:23
23        return 0; /* set break here */

<enter is pressed here>
Will stop next time breakpoint 2 is reached.  Continuing.

*commands here are ignored here, the inferior running in the foreground*
