OK, let's try to reproduce that:

> x1 <- runif(1000)
> x2 <- runif(1000)
> x3 <- runif(1000)
> x4 <- runif(1000)
> x5 <- runif(1000)
> x6 <- runif(1000)
> x7 <- runif(1000)
> x8 <- runif(1000)
> y <- rnorm(1000)
> fit <- lm(y~(x1*x2*x3*x4*x5*x6*x7*x8)^2)
No crash, a quite reasonable fit.

Can we please have a reproducible example, as we do ask?
