It is starting to look like an issue in Cython, the old gmp 4.2.1+Nils
Moeller patches also shows the leak in Sage.

Can you write a test and check it in? I am not sure if anyone added
one yet.
I am valgrinding all of the Sage doctests against the eMPIRe svn, so
if there is something either in leak form or some invalid access, etc,
it will likely pick it up. This will take a couple CPU days, but since
I am using 12 cores I should know in less than 8 hours :)
Cheers,
Michael
