Comment (by pbruin):
The problem seems to lie in `sage/rings/integer.pyx:fast_tp_new()`, where
the call to `mpz_alloc()` is not surrounded by `sig_on()...sig_off()`.
This should be fixed, but it probably won't help in this specific example,
because Sage has runs hopelessly out of memory. I tried it twice with the
`sig_on()...sig_off()` added, and Sage still crashes, just not with the
same error message; once it was killed by IPython with a `MemoryError`,
once by Sage's `c_lib/src/interrupt.c:sigdie()`, presumably because
another out of memory error occurs during signal handling.
