This is already reported upstream at
[https://sourceforge.net/tracker/?func=detail&aid=3587932&group_id=4933&atid=104933
this bug tracker ticket].
The original report from a summer PREP user:
{{{
integral((2/3)*x^(5/2)*(x+1)^.5, x,0,1)
I got the answer -0.888888889*sqrt(2)
integral((2/3)*x^(5/2)*(x+1)^(1/2), x,0,1)
And the answer is
-5/192*I*pi + 61/288*sqrt(2) + 5/192*log(-sqrt(2) + 1) -
5/192*log(sqrt(2) + 1)
}}}
