---------------------------+------------------------------------------------
Reporter: mhansen | Owner: mhansen
Type: defect | Status: new
Priority: major | Milestone: sage-3.4.1
Component: combinatorics | Keywords:

Comment(by mabshoff):
I did glance over the patch and this is also something that needs to be
fixed for 32 bit boxen:
{{{
182 def __hash__(self):
183 """
184 EXAMPLES::
185
186 sage: e = RootSystem(['A',2]).ambient_space()
187 sage: hash(e.simple_root(0))
188 -4601450286177489034 # 64-bit
}}}
I am also not yet 100% convinced that '''@cached_method''' does not cause
memory leaks, but I have no evidence or test case to prove my suspicion :)
Cheers,
Michael
