Trying to close a jpeg() device on an Intel Mac causes the following:

JPEG parameter struct mismatch: library thinks size is 372, caller expects 376
null device
          1

An empty jpg file is produced in 'out.jpg'                                      
-

AFAICT, this wouldn't be a bug in R. Your version of R appears to
have been built with one version of the jpeg libraries and you have
another version installed. Unless we have a compiler issue and one
part is padding out to a multiple of 8 bytes.

Although it's not a bug in R, it is a problem with the Mac binary  
which uses static libjpeg. I have re-compiled libjpeg for Intel Mac  
so tonight's nightly build should be ok.

Thanks,
