8.6.0.1.0. (xerbla srname info )

* =====================================================================
* Purpose
* =======
*
* XERBLA is an error handler for the LAPACK routines.
* It is called by an LAPACK routine if an input parameter has an
* invalid value. A message is printed and execution stops.
*
* Installers may consider modifying the STOP statement in order to
* call system-specific exception-handling facilities.
*
* Arguments
* =========
*
* SRNAME (input) CHARACTER*6
* The name of the routine which called XERBLA.
*
* INFO (input) INTEGER
* The position of the invalid parameter in the parameter list
* of the calling routine.
