### could someone try this integral?

Could someone please try this integral on their PC? I am getting sage core dump from it.

Wanted to see if it just my sage or if it happens to others

sage: integrate(x^m/sqrt(a + b*x^(2 - m)),x)

;;; Jumping to the outermost toplevel prompt

When I use other algorithm, no core dump

sage: integrate(x^m/sqrt(a + b*x^(2 - m)),x,algorithm="giac")
integrate(x^m/sqrt(b*x^(-m + 2) + a), x)


I am on Linux Manjaro 17.1. Intel PC. Installed sage, compiled from sources, using Manjaro package manager pacman.

And just in case, I also posted bug report here https://trac.sagemath.org/ticket/25636

Thank you
