[R] R 2.10.0: Error in gsub/calloc

[Gabor Grothendieck]

Note that you don't need perl = T since by default strapply uses tcl
regular expressions and they support \w.  What happens if you omit the
perl = T?

Also please specify the version of gsubfn you are using and if its not
the latest then try it with the latest version.
