Comment(by SimonKing):
Using `trace`, it seems to me that the error occurs in line 245 of
`sage/matrix/matrix_space.py`:
{{{
if nrows >= 2**63 or ncols >= 2**63:
}}}
Is computing `2**63` (with Python ints) a problem on 32 bit?? Apparently
not:
{{{
sage: int(2)**int(63)
9223372036854775808L
}}}
So, the problem isn't solved, yet.
