Description
When trying to follow the basic instructions on the README, I get a core dump the moment I try to do any calculation:
from numpy_quaddtype import QuadPrecDType
import numpy as np
a = np.array([1,2,3], dtype=QuadPrecDType())
a
array([QuadPrecision('1.0e+000', backend='sleef'),
QuadPrecision('2.0e+000', backend='sleef'),
QuadPrecision('3.0e+000', backend='sleef')],
dtype=QuadPrecDType(backend='sleef')
b = a+a
Illegal instruction (core dumped)
Things do seem to work with the longdouble backend.
I tried to install the source code (i.e., also compile sleef on my machine), but that gives the same error.
In case it helps, my numpy runtime:
import numpy; numpy.show_runtime()
