@StephenLuttrell This is a useful observation however the problem that DSolve yields generic solutions remains.

I mean since $y(x)=e^x$ is a special solution to the ODE, then the ODE with initial condition is not incompatible and the current solving approach DSolve uses may be inappropriate.

Can we know how the DSolve works? Is the general solution, $y(x)=e^x+\dfrac{1}{c-x}$, correct? Since $y(x)=e^x$ is obviously a special solution to the ODE, which can be easily verified.
