[petsc-users] what kind of stuffs I forget to free?

[Fande Kong]

Hi Jed,

I finally figured out why. I think there is a bug in the PETSc. I write a
very simple program that can reproduce the same results. Please check the
attachment. Type " make all -f makefilet " to run this code. Could you know
how to fix this issue?

Thanks,
