I get the same result on bsd.math (Mac OS X 10.6.2). Doing a verbose
long doctest, I get:
Trying:
Integer(1) < l11###line 213:_sage_ >>> 1 < l11
Expecting:
False
------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occured in SAGE.
This probably occured because a *compiled* component
of SAGE has a bug in it (typically accessing invalid memory)
or is not properly wrapped with _sig_on, _sig_off.
You might want to run SAGE under gdb with 'sage -gdb' to debug this.
SAGE will now terminate (sorry).

The following tests failed:
sage -t -verbose -long
"devel/sage-main/sage/structure/element_wrapper.py"
The relevant doctest from sage/structure/element_wrapper.py that
causes the segfault is:
sage: class MyElement(ElementWrapper):
... __lt__ = ElementWrapper._lt_by_value
...
sage: parent1 = ZZ
sage: parent2 = QQ
sage: l11 = MyElement(1, parent = parent1)
sage: l12 = MyElement(2, parent = parent1)
sage: l21 = MyElement(1, parent = parent2)
sage: l22 = MyElement(2, parent = parent2)
sage: l11 < l11
False
sage: l11 < l12, l12 < l11 # values differ
(True, False)
sage: l11 < l21 # parents differ
False
sage: l11 < 1 # class differ
False
sage: 1 < l11
False
