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.
Parameters
[in]SRNAME
          SRNAME is CHARACTER*(*)
          The name of the routine which called XERBLA.
[in]INFO
          INFO is INTEGER
          The position of the invalid parameter in the parameter list
          of the calling routine.
