Now that I look back, I am pleased to read that this problem was reported to be "fixed" in 2007.

Note: Wolfram Alpha gets this definite integral correct.

different problem?

Compared with that comment, the symptoms here are different:

> f:=sqrt(-8*cos(t)*sin(t)+5):a:=0:b:=2*Pi:
> `int/definite/elliptic`(f,t,a,b,{});
memory used=37.4MB, alloc=43.1MB, time=0.60
                                      FAIL
> `int/definite/ftoc`(f,t,a,b,{}); 
                                       0

So, it may be a different bug yet to be fixed.
