    34  *> XERBLA  is an error handler for the LAPACK routines.
    35  *> It is called by an LAPACK routine if an input parameter has an
    36  *> invalid value.  A message is printed and execution stops.
    37  *>
    38  *> Installers may consider modifying the STOP statement in order to
    39  *> call system-specific exception-handling facilities.
