What is all the above supposed to mean?

Does this really have anything to do with mpl::at_c, as the subject implies? It looks like it's all about tuples. Also, is it the Boost implementation of tr1 or some other vendor's? If you have found a bug, please enter a ticket by following the newticket link at http://svn.boost.org/trac/boost. Thanks.

Hi all -- Just to say I encountered what looks to be the same problem. Here is the note I left myself:

// can later access the statistics as follows: // // std::tr1::tuple stats; // stats = myTs.getStats(); // int count; // count = stats.get<0>(); // member function usage (could be buggy) // count = std::tr1::get<0>(stats); // free function usage

Also:

#include // n-tuples

I relealize this is the TR1 version and not the Boost version. Please let me know if some stripped down example code would be useful.

My development environment for the record:

boost : 1.34.1 (via ./configure; make all; make install) gcc : 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5) os : Ubuntu 6.10, Linux 2.6.17-12-generic (7.04 is current) hardware : Toshiba Tecra A2 330 laptop (purchased Aug-2004)
