[boost] [bigint] operator< problem

Hello I have the problem with boost::bigint (from boost-sandbox). There's minimal example: #include "boost/bigint.hpp" int main (void) { boost::bigint b = 1; while ( b < 1001 ) b *= 10; } Loop never ends; is it known issue? Compiler g++ 3.4.2 (mingw) -- Regards, Janusz
