[petsc-dev] PCASM+KSPGMRES

Hi again,

 > Well, I don't usually use PETSc  runtime options. I have only a 
subset of parameters (PC types, KSP types, etc.) which are interfaced by 
my solver and exposed to the end-user. Other few settings (matrix types 
for instance) are hardcoded in some objects (which my linear system 
solver interface makes use of).

Thanks for sending the hardcoded options, I could reproduce the problem 
with snes/examples/tutorials/ex2.c using the runtime options
  -pc_type asm -vec_type cusp -mat_type aijcusp
Actually, the problem can be reduced down to only providing
  -vec_type cusp

It seems to be the same problem as the one described here:
which I couldn't track down yet. I'll let you know as soon as this is fixed.

Best regards,
