Research direction
Start by reproducing expintx(complex(-x)) with x above roughly 700, then inspect the expintx implementation and its suspected expinti path. No file or test is named in the issue; done means these large negative real arguments no longer return NaN and the behavior is covered by an appropriate regression test.
Written by the indexing model from the issue text.
Description
expintx(complex(-x)) returns NaN for x more than around 700. It's almost like this is being handled by -exp(-x)*expinti(x) and we're getting an overflow error.
