# bus or segmentation fault calling integrate

Why does sagemath crash on this integrate? Running this inside Linux Manjaro in a VBox.

```
>sage
┌────────────────────────────────────────────────────────────────────┐
│ SageMath version 8.9, Release Date: 2019-09-29 │
│ Using Python 2.7.16. Type "help()" for help. │
└────────────────────────────────────────────────────────────────────┘
sage: var('a b c d e f m n p x ')
(a, b, c, d, e, f, m, n, p, x)
sage: integrate((c*cos(b*x+a)^m)^(3/2),x)
```

And after about 20-30 seconds sagemath crashes

```
;;;
;;; Detected access to protected memory, also kwown as 'bus or segmentation fault'.
;;; Jumping to the outermost toplevel prompt

```

Strange thing is it crashes when exponent is `3/2`

but not when exponent is `5/2`

I remember seeing such crashes in sagemath before, but I thought this was fixed.

Is this a known bug or something new?
