R, Macports and C++ streams

Dear all, R on Macports relies on GCC 4.3 to build packages. I find that packages with shared objects that use C++ streams crash R if they're compiled using Macports' gcc43, but work fine if compiled in exactly the same way using Apple-supplied GCC 4.2. Has anyone here had the same issue/know what is causing this problem?
Using compilers from MacPorts and similar suites (Darwin ports, Fink etc.) is strongly discouraged (and outright not supported by the CRAN binary) since they have been known to be badly broken in the past and when whenever tested so far they were incomplete and incompatible. You have to re-compile R yourself with those tools (and you're entirely on your own) if you really want to use them. CRAN binaries work only with Apple's gcc branches, if you want to use anything else, you have to follow the unix R instructions and compile everything from sources.
Dear Kjell, As you can see above, your R port on Macports appears to be broken and has a reputation of having been broken for a while. I for one have experienced odd problems as described above. To avoid further issues with unsuspecting Macports users, perhaps it would be good to pull the port from the repository until a decent level of reliability can be provided ? Cheers, Ernest
