Summary: code that generates a segfault on Python 2.1-2.3

Initial Comment:
On a Redhat Linux 9 based system, the following causes
a segfault:


""" In python, you can call any expression.
"""

class foo:
  def __init__(s,times=1):
     s.times = times
  def __call__(s): print s.times
  def __mul__(s,o): return foo(o)
  def __coerce__(s,o):
    if isinstance(o,int):
      return o,s


(foo(3)*10)()   # no segfault
 
(10*foo(3))()   # segfaults
# prints 10
