odeint with empty derivative vector causes segmentation fault #13276
Labels
defect
A clear bug or issue that prevents SciPy from being installed or used as expected
scipy.integrate
The crash seems to happen in
xerrwv
, called fromlsoda
(see backtrace below).solve_ivp
handles the empty derivative vector case fine (see output below).I found this while investigating the behaviour of
signal.lsim2
for feedthrough (empty ABC matrix) systems; callinglsim2
with such a feedthrough system results in this crash.Reproducing code example:
