#14549: Memory leak in algebraic_immunity of BooleanFunction class
----------------------------+-----------------------------------------------
Reporter: okazymyrov | Owner: mvngu

Component: cryptography | Keywords: algebraic_immunity,

----------------------------+-----------------------------------------------
On my Mac OS X 10.8.3 the code
{{{
from sage.crypto.boolean_function import BooleanFunction
s=[BooleanFunction(random_vector(GF(2),16).list()).algebraic_immunity()
for g in xrange(100)]
s=[BooleanFunction(random_vector(GF(2),16).list()).algebraic_immunity()
for g in xrange(100)]
}}}
takes around 5GB of RAM on each "s=..." part. You can repeat the procedure
for new 5GB.
Without algebraic_immunity function, the problem disappears.
