Hi Peter and Rolf,
Many thanks for all!
The "bug" was just found: it is related with the package AlgDesign!
(and I've been loading it from Rprofile.site already for a long long time). :-(
See below:

Call:

Terms:
Species Residuals
Sum of Squares 63 39
Deg. of Freedom 2 147
Residual standard error: 0.51

> library(AlgDesign)
> aov(Sepal.Length ~ Species, data=iris)
Error in parse(text = x) :
unexpected symbol in "Sepal(Sepal.Length+Species)Length"
I wonder it is really a small bug. Do you agree?
All the best,
