The following code consistently crashes Python 2.4 on Mac OS X:

import threading

class foo:
    def __getattr__(self, x): self.foo

def j(): foo().bar

t = threading.Thread(target=j, args=())
t.start()

I've also tested it on FreeBSD and it has the same problem (Segmentation fault 
(core dumped)).

Logged In: YES

Since the indenting was off above, I've attached the code.

Hello.

I have the same segfault :-(

Python version: from SVN
Python 2.5a0 (trunk, Feb 19 2006, 22:22:12)
[GCC 3.4.4 [FreeBSD] 20050518] on freebsd6

Best regards, Alexander.

I can still reproduce this on FreeBSD 7.0 BETA2.

Python version is
Python 2.5.1 (r251:54863, Nov 14 2007, 13:09:04) 
[GCC 4.2.1 20070719  [FreeBSD]] on freebsd7

And under 2.6 on OS X.  I doubt this is a BSD thing but more of a
recursion depth issue.

And I don't think there is anything to fix here.  The recursion depth is
a per-thread thing, and this test is blowing the C stack before the
recursion depth is reached.  If you drop the recursion limit lower the
proper exception is raised (I had to drop mine down to 400 to trigger
the exception).

So this is not a Python issue, per-se, just a limitation of the C stack
and how things are implemented.  While we do everything we can to
prevent crashes, this just can't be helped as the C stack is not under
our control.

Closing as invalid.
