Mathematica: cpu = 0.006001 (sec), leaf count = 33 $$\left\{\{y(x)\to c_1{D}_{-1}\left(\sqrt{2}x\right)+c_2{D}_0\left(i\sqrt{2}x\right)\}\right\}$$

Maple: cpu = 0.031 (sec), leaf count = 23 $$\{y\left(x\right)=\mathit{\_}\mathit{C}\mathit{1}{\mathrm{e}}^{\frac{x^2}{2}}+\mathit{\_}\mathit{C}\mathit{2}{\mathrm{e}}^{\frac{x^2}{2}}\mathit{E}\mathit{r}\mathit{f}\left(x\right)\}$$
