Comment:
I confirm the failure on 32-bit computers with Sage 4.7.1, where the patch
applies smoothly.
However there are already some tests that are known to fail on 32-bit, for
example
in {{{lib/cremona/newforms.pyx}}}:
{{{
sage: from sage.libs.cremona.newforms import ECModularSymbol
sage: E = EllipticCurve('858k2')
sage: ECModularSymbol(E)
Traceback (most recent call last): #
32-bit
... #
32-bit
OverflowError: long int too large to convert to int #
32-bit
}}}
Should we mark the tests which are failing on 32-bit in the same way?
