Hi

I am trying  to debug a segmentation fault when sending the message 
NSWindow>>setTitle:
>From gdb the backtrace is:

...
#5  <signal handler called>
#6  0x002185ab in objc_msg_lookup () from /usr/lib/libobjc.so.2
#7  0x008200e1 in -[NSWindow setTitle:] (self=0x8477c28, _cmd=0x9fb128, 
aString=0x852b338) at NSWindow.m:1203
...

The frame 7 is stuck in the first message send:
1203      if ([_windowTitle isEqual: aString] == NO)

But every thing seems normal:

(gdb) p _windowTitle
$5 = (struct NSString *) 0x65637275
(gdb) po 0x852b338
<unnamed class> new "0x852b338"


If someone have an idea?

Thanks a lot

--Mathieu
