[petsc-users] KSPSolve crashes with petsc-3.5.1

[Alexander Grayver]

Dear PETSc devs,

I am getting the following error with petsc-3.5.1:

[0]PETSC ERROR: --------------------- Error Message --------------------------------------------------------------

I have used LSQR here which was setup in the following way:

  KSPCreate(communicator, &ksp);
  KSPSetType(ksp, KSPLSQR);
  KSPSetTolerances(ksp, tol, PETSC_DEFAULT, PETSC_DEFAULT, max_iterations);
  KSPSetFromOptions(ksp);
  KSPGetPC(ksp, &pc);
  PCSetType(pc, PCNONE);
  KSPSetOperators(ksp, A, PETSC_NULL);
  KSPSolve(ksp, b, x);

The code works fine with petsc-3.4.4 (provided that I pass DIFFERENT_NONZERO_PATTERN to the KSPSetFromOptions). Any idea?

Regards,
Alexander
