[petsc-users] KSPSolve crash

[Qin Lu]

PETSc team,

I have a program using PETSc linear solver (using KSPBCG with PCILU level 0). But with one case it crashed inside KSPSolve without any error message. I have tested this program with many other cases successfully.

Could you debug PETSc with the linear system? I can send you the matrix and rhs if you let me know where to upload them.

Many thanks,
Qin
