imports properly in windows R x64 3.0.1 but causes R x64 3.0.2 to crash


the crash occurs at the line

rval <- .External(do_readStata, file)


at the bottom of this e-mail, i have included code that will reproduce the
problem exactly in 3.0.2 but not 3.0.1


and if i don't load the memisc and Hmisc packages, i get an error instead
of a crash..

> x <- read.dta( fp , convert.factors = FALSE )Error in read.dta(fp, convert.factors = FALSE) :
  Value of SET_STRING_ELT() must be a 'CHARSXP' not a 'NULL'


..but if i load both (as shown in the script below), R just dies.

[R] reading in stata file with read.dta works in R x64 3.0.1 and crashes R x64 3.0.2

See the posting guide: your version of 'foreign' is not current: 
http://cran.r-project.org/web/packages/foreign/index.html .

Please update your packages and try again.  (This looks very like a bug 
in recently contributed code that has already been fixed.)
