weird error with big columns #327

Open beckermr opened 3 years ago

beckermr commented 3 years ago

I cannot tell if this is a cfitsio error or something else, but here it is:

import fitsio
import numpy as np

d = np.ones(1, dtype=[("blah", "S35000")])

fitsio.write("test.fits", d, clobber=True)

produces

If its a limit in cfitsio then we should probably just provide a better error message. This one makes it seem like there is an inconsistency in the data
