There appears to be a memory leak when repeatedly calling binomial with
different parameters. This sometimes also appears when the parameters to
binomial are not varied, but is not consistent. This is a problem for the
Combinations rank code, which makes many repeated calls to binomial.
{{{
sage: import random
print get_memory_usage()
for i in xrange(100000):
x=random.randint(10,100)
y=random.randint(0,x)
r=binomial(x,y)
print get_memory_usage()
730.6328125
736.5625
}}}
The output is from running the code in Sage 4.1 on sagenb.org. I think
the same problem may involve the symbolic backend and GiNaC, since the
same problem also occurs with log.
