The bug appears to be tickled by the Maxima package abs_integrate.
Without abs_integrate, integrate(sqrt(1 + cos(x)^2), x, 0, %pi) just
returns a noun expression.

Running sage in cocalc:
integral(sqrt(1+cos(x)^2),x,0,pi)
0
Zero is decidedly not correct. The problem is apparently here:
integral(sqrt(1+cos(x)^2),x)
-1/24*sin(3*x) + 1/8*sin(x)

Hello,
gfortran is installed but sage still doesn't work. I do

Or waiting for Sage 8.1 since that problem has been fixed in the mean time.
