When we repeat a command, by just pressing <ret>, the input from the previous command is reused for the new command invocation. When an execution command strips the "&" out of its incoming argument string, to detect background execution, we poke a '\0' directly to the incoming argument string. Combine both, and a repeat of a background command loses the "&". This is actually only visible if args other than "&" are specified (e.g., "c 1&" or "next 2&" or "c -a&"), as in the special case of "&" alone (e.g. "c&") doesn't actually clobber the incoming string. Fix this by making strip_bg_char return a new string instead of poking a hole in the input string. New test included. Tested on x86_64 Fedora 20, native and gdbserver. gdb/ 2014-10-17 Pedro Alves <palves@redhat.com> PR gdb/17471 * infcmd.c (strip_bg_char): Change prototype and rewrite. Now returns a copy of the input. (run_command_1, continue_command, step_1, jump_command) (signal_command, until_command, advance_command, finish_command) (attach_command): Adjust and install a cleanup to free the stripped args. gdb/testsuite/ 2014-10-17 Pedro Alves <palves@redhat.com> PR gdb/17471 * gdb.base/bg-execution-repeat.c: New file. * gdb.base/bg-execution-repeat.exp: New file.
