[petsc-dev] GMRES with one processor crashes

[Alexander Grayver]

I tested various combinations, for the error.

It appears only in this combination:

* debugging configuration
* MKL blas/lapack (but not blacs and scalapack!)
* development branch

The release configuration, reference blas/lapack installation or 
petsc-3.2-p5 do not have the problem.

Regards,
Alexander
