Please give a _reproducible_ example on the current version of R (2.0.0). It works fine for me using the example in ?ppr:

> rock.ppr <- ppr(log(perm) ~ area1 + peri1 + shape,

+                      data = rock, nterms = 2, max.terms = 5, optlevel=0)

> rock.ppr
> rock.ppr <- ppr(log(perm) ~ area1 + peri1 + shape,
sm.method="gcvspline", + data = rock, nterms = 2, max.terms = 5, optlevel=0)

Neither of the above crashes, nor gave any error.

WinXP Pro with R-2.0.0.
