Stopped status is reported as exit by 32-bit linux lldb

Hi,

With a recent build of 32-bit linux lldb, tracer stop being
sent to the inferior results in lldb erroneously reporting
that the inferior has exit:

$ lldb hello
Current executable set to 'hello' (i386).
(lldb) run
Process 2115 launching
Process 2115 stopped
* thread #1: tid = 2115, 0x00000000, name = 'hello', stop reason = trace
     frame #0: 0x00000000
error: Input/output error
(lldb) Process 2115 launched: '/home/mg11/src/play/clang-tests/hello/hello' (i386)
Hello from test program!!
(lldb) process interrupt
Process 2115 exited with status = 0 (0x00000000)

But the kernel reports the following about the inferior:

$ cat /proc/2115/status
Name: hello
State: t (tracing stop)
Tgid: 2115
Pid: 2115
PPid: 2108
TracerPid: 2114
...

The statement "Process 2115 exited with status = 0 (0x00000000)" is
wrong.

thanks
