Details:
Dear developers
when calling
[t,x]=ode45(@(t,x)1+x.^2,[0,2],0)
Octave does not return to prompt at all
while
[t,x]=ode45(@(t,x)1+x.^2,[0,1],0)
leads to a correct result
The exact solution of the ODE is x(t) = tan(t)
Thus the failing situation is running into a blowup of the solution.
The "old" package odepkg solves the problem with an appropriate warning
message.
