On entry to DGEMV parameter number 6 had an illegal value

   This an error message from BLAS.

   BLAS has a terrible model for error handling; it just prints
a message to screen that you cannot control and does not
return an error code :-(

    Are you
1) using a BAIJ matrix with a block size bigger than 8?
2) the bcgsl KSP solver or
3) dense matrices (how do you create the dense matrix?)
4) are you using 64bit integers (very unlikely)

   The best thing to do is run in the debugger to see when/where/why
this is happening.
