I have a bug report on that compiler (Sparc, Solaris 9) that I don't have any way to reproduce.
It is reproducable on one of the machines [1] I have access to at my university (Solaris 10, sparc, SunStudio 12) with the command line [2] and test program [3] shown below, producing the below errors [4], where :351 and :358 are the definitions of the free c_array functions of Boost.Array.

Yeah - it's complaining about a method in boost::array: // Specific for boost::array: simply returns its elems data member. template <typename T, std::size_t N> T(&get_c_array(boost::array<T,N>& arg))[N] { return arg.elems; } I don't see any subscript operators there at all. ;-) I suspect that this is a limitation of the compiler. Here's a standalone test case:
#include <boost/array.hpp>
int main(int argc, char *argv[]) { boost::array<int,5> arr; return 0; }
