[Rd] Rcurl crash in R-devel

[Marc Girondot]

Update taking into account the answer of Prof Ripley.
___________________________________________________

Below is a reproducing example that produces the crash.
If I do exactly the same in R 3.1.2, it works perfectly.

I have the lastest libcurl library (curl @7.40.0) installed

So, perhaps indeed that the problem originates from RCurl, but the 
problem appears only in R 3.2.

But before to check more carefully, I would like to know if others have 
also a problem using the same configuration : MacOS X 10.10.2 and R 3.2 
or if it is only for me ?

Sincerely,

Marc
