Debugging a program under Darwin does not work:
(gdb) start
Temporary breakpoint 1 at 0x100000fb4: file /tmp/helloworld.c, line 1.
Starting program: /private/tmp/helloworld
[New Thread 0x2903 of process 60326]
During startup program terminated with signal SIGTRAP, Trace/breakpoint trap.
Field signaled from darwin_thread_info is not initialized thus signal sent to
the debuggee is considered as not sent by GDB whereas it should.
This patch fixes this problem.
gdb/ChangeLog:
* darwin-nat.c (darwin_check_new_threads): Initialize signaled
field.
