Bug#944648: sagemath FTBFS on i386

[Tobias Hansen]

Source: sagemath
Version: 8.9-2
Severity: serious

Since the switch to Python 3 in 8.9~beta9-1, sagemath fails to build from source on i386. The reason are segmentation faults in the following three tests:

sage -t --long src/sage/schemes/elliptic_curves/isogeny_small_degree.py  # Killed due to segmentation fault
sage -t --long src/sage/schemes/elliptic_curves/ell_number_field.py  # Killed due to abort
sage -t --long src/sage/schemes/elliptic_curves/ell_field.py  # Killed due to segmentation fault

All three failures give the error message

OverflowError: Python int too large to convert to C long

from

File "sage/rings/polynomial/polynomial_integer_dense_flint.pyx", line 284, in sage.rings.polynomial.polynomial_integer_dense_flint.Polynomial_integer_dense_flint.__init__ (build/cythonized/sage/rings/polynomial/polynomial_integer_dense_flint.cpp:6548)
        fmpz_poly_set_coeff_si(self.__poly, i, a)

Help on finding a fix would be appreciated.

Best,
Tobias
