[Bug gdb/10449] New: continues main thread when breaking into a secondary thread

[apaku at gmx dot de]

I've got a small test application here creating a GUI in the main thread and
starting two new threads within the window constructor. In both threads there's
a sleep() (one with 2 the other with 4 seconds) to keep them running a bit.

I then put a breakpoint at the start of the constructor and into the 4-second-
seems to continue the main thread once the breakpoint in the 4-second-sleep
thread is hit. So basically the order is:

create and start first extra thread
<n>
create and start second extra thread
<n>
some gui code
<n>
break into second extra thread
<n>
sleep(4)
<n>

At this point the gui from the main thread comes up, which only happens if the
main thread is continue'd and not halted anymore.

Yes, a "next" will resume all other threads.
See "set scheduler-locking" for your options here.
(I forget offhand if this was in 6.8 or whether it is only in CVS gdb.)

scheduler-locking was added to gdb over 10 years ago.

I'm closing this.  Please reopen if you have more info indicating a problem.
