Actually, it did. I didn't quote the message exactly (as I said). Now, I took the liberty to make my own suggested change in R-devel_2005-08-28 and rebuilt, and you may guess what error message I got.;)

Error in coxreg.fit(X, Y, rs, strats, offset, init, max.survs, method, :

        The BLAS/LAPACK routine 'DSYR ' gave error code -7

BTW, the original BLAS xerbla (from the netlib page you referred to) gives the message:

     WRITE( *, FMT = 9999 )SRNAME, INFO
9999 FORMAT( ' ** On entry to ', A6, ' parameter number ', I2, ' had ',

     $ 'an illegal value' )

which I think is even better than my original suggestion. (Why was it changed?)
