            Bug ID: 17067
           Summary: Cannot send a signal to a thread because the thread is
                    running.
           Product: gdb
           Version: 7.6
            Status: NEW
          Severity: normal
          Priority: P2
         Component: threads
          Assignee: unassigned at sourceware dot org
          Reporter: hi-angel at yandex dot ru

I m trying to send a signal to a thread in order to break the one. But I get an
error. Below is how it looks like:
(gdb) thread apply 4 signal SIGTSTP                                             

Thread 4 (Thread 0x7ffff5fd4700 (LWP 5826)):
Cannot execute this command while the selected thread is running.

It is surely should be possible http://linux.die.net/man/3/pthread_kill
Also I should mention that this is very needed feature, because it is the only
way to pause a particular thread -- for unknown reasons the gdb doesn't support
any other path.

--- Comment #1 from Pedro Alves <palves at redhat dot com> ---
You want "interrupt", not "signal".

(gdb) help signal 
Continue program with the specified signal.
Usage: signal SIGNAL
The SIGNAL argument is processed the same as the handle command.

An argument of "0" means continue the program without sending it a signal.
This is useful in cases where the program stopped because of a signal,
and you want to resume the program while discarding the signal.

(gdb) help interrupt 
Interrupt the execution of the debugged program.
If non-stop mode is enabled, interrupt only the current thread,
otherwise all the threads in the program are stopped.  To 
interrupt all running threads in non-stop mode, use the -a option.
