I don't believe your message actually came from R's XERBLA.  Note that the=

name is not quoted and that the name of the routine is not 6 characters=20
long.

Here is a genuine example from R:

Error in La.svd(x, nu, nv) : LAPACK routine 'DGEBRD' gave error code -10

There is no R 2.2.0, BTW.  If referring to R-devel, please do so with an=20

Some BLAS routines call xerbla for error messages, which results in a mes=

sage

like
"LAPACK routine DGER gave error code -9".

Suggested solution: In

void F77_NAME(xerbla)(char *srname, int *info)
{
  /* srname is not null-terminated.  It should be 6 characters. */
   char buf[7];
   strncpy(buf, srname, 6);
   buf[6] =3D '\0';
   error(_("LAPACK routine '%6s' gave error code %d"), buf, -(*info));
}

change 'LAPACK' to 'The' (or 'The BLAS/LAPACK').
