Comment (by zimmerma):
with 6.0 both work but take a long time:
{{{
sage: sage.calculus.calculus.maxima('domain: real')
real
sage: integrate(exp(-x)*sinh(sqrt(x)), x, 0, oo)
1/4*sqrt(pi)*(erf(1) - 1)*e^(1/4) - 1/4*(sqrt(pi)*(erf(1) - 1) - sqrt(pi)
+ 2*e^(-1) - 2)*e^(1/4) + 1/4*sqrt(pi)*e^(1/4) - 1/2*e^(1/4) +
1/2*e^(-3/4)
sage: sage.calculus.calculus.maxima('domain: complex')
complex
sage: integrate(exp(-x)*sinh(sqrt(x)), x, 0, oo)
1/4*(sqrt(pi)*(erf(1) - 1) + sqrt(pi) + 2*e^(-1) - 2)*e^(1/4) -
1/4*(sqrt(pi)*(erf(1) - 1) - sqrt(pi) + 2*e^(-1) - 2)*e^(1/4)
}}}
