New submission from Max Kaye:
Python 2.7.3 (v2.7.3:70274d53c1dd, Apr 9 2012, 20:52:43)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> print round(1.123456, 3)
1.123
>>> print round(1.123756, 3)
Segmentation fault: 11
This doesn't happen if you just do the second round, only if you do both.
`python -c "print round(1.123456, 3); print round(1.123756, 3)"` doesn't segfault.
Doesn't segfault on brew's python:
Python 2.7.3 (default, May 19 2013, 04:22:38)
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.51)] on darwin

>>> print round(1.123456, 3)
1.123
>>> print round(1.123756, 3)
1.124
>>>
Doesn't segfault on another box:
Python 2.7.2+ (default, Jul 20 2012, 22:12:53)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
