Windows, eh? Which version of R? 

It might be a memory corruption bug of some sort, but without the
actual dataset it will be difficult to reproduce.

Does the same thing happen with the built-in data sets (e.g.
airquality), like

data(airquality)
dim(airquality)
summary(airquality)
attach(airquality)
slm<-lm(Ozone~Temp,airquality)

which would seem to be equivalent to your example (and doesn't crash
for me). 

Is your example the *entire* set of statements leading to the error
condition or might there be strange things going on earlier on?
Accidentally redefining a function may lead also to this kind of
effect.

One useful thing would be to issue a traceback() when the error
occurs, which should tell you which function the error occurred in.
Then one might set a debug() on the function and single step.
