[R] Reading of a large SAS Export dataset

I am trying to read in a large SAS dataset (1706 observations, 72 
variables)  using the foreign package.

R crashes, with the error message "This program has performed an 
illegal operation and will be shut down."  The details given include
"RGUI caused an invalid page fault in module FOREIGN.DLL at 
015f:14c327e7."

Bearing in mind the statement on p.2 of the R Data Import/Export 
document, "In general, statistical systems like R are not 
particularly well suited to manipulations of large-scale data," I 
must reluctantly conclude that my dataset is too large to be 
handled by R.

Confirmation of this would save me a lot of time spent in futile 
further attempts at achieving the impossible.

Many thanks again in advance.
