Description (last modified by Thierry Monteil)

As reported on this ask question, the commands


produce the output

1/4*(((-1)^n - 1)*gamma(n + 1, I*x) - ((-1)^n - 1)*gamma(n + 1, -I*x))*(-1)^(-1/2*n)

which is identically zero for n even. Possibly an issue with branches of exponential integrals. Possibly related to #17968.
