[petsc-dev] misleading error message in VecWAXPY

[Blaise Bourdin]

Hi,

It looks like when VecWAXPY is called with alpha=Nan, PetscValidLogicalCollectiveScalar causes the message "Scalar value must be same on all processes, argument # 2" to be printed. This is a bit misleading, and confusing when running on only 1 processor.

Is this something worth fixing?
