Hello,

I don't know if the problem originates from R-devel 3.2 or Rcurl itself. I post this message to the R-devel list and to the author of RCurl (dun...@r-project.org).

 *** caught segfault ***
address 0x0, cause 'memory not mapped'

Traceback:
1: .Call("R_curl_easy_perform", curl, .opts, isProtected, .encoding, PACKAGE = "RCurl") 2: curlPerform(url = to, upload = TRUE, readfunction = uploadFunctionHandler(file, asText), ..., curl = curl)
 3: ftpUpload(what = filepath, to = urlx)

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection:

Hope it will help,

Sincerely,

Marc
