First, I didn’t. But for getting some output from the functions in 
attributes.cpp I later compiled the Rcpp package from source. When I compile 
with the option “-headerpad_max_install_names” the compileAttributes runs 
without an error. If I compile without this flag, I get the pointer error. 
Problems with header padding is a well-known issue on the Mac 
(https://svn.boost.org/trac/boost/ticket/1927), usually in frameworks. It is 
used a relative path in the sections of shared objects (sometimes also in 
dynamic libs). When the library/shared object has to be included in other 
libraries, the relative path has to be changed to an absolute path. If then 
there is not enough space in the header of the Mach-O file, it gives you an 
exception. 

But my guess is for the compileAttributes function, that no library binding is 
done, though it takes library paths as arguments when calling ‘.Call’. My 
perception has been so far, that this function solely creates the 
RcppExports.cpp and *.R files without any compilation or linking (this is done 
later, when we compile the package with the attributes). The depends/linkingto 
names from the DESCRIPTION file are used for headers in the RcppExports.cpp 
file I have guessed. The point, that I am seemingly the only one, that 
encounters this error, points me to my compiler (gcc4.8.2). Could be, that 
under the hood clang uses already a larger header padding. 

Btw: When you are on Mac, could you check what “otool -L Rcpp.so” give you? Is 
the path relative (Rcpp.so) or absolute (has it something like @exectuable_path 
in front)?
