Hello! I've been debugging my application that uses Boost.Locale for the past five hours or so, and I've found it curious that it leaks memory. In order to stop it, I have to do a couple of weird things, such as including ICU in to my projects and calling u_cleanup at the end of my application. I also have to disable certain facets. I've put all this together in some source code, that by default won't leak, but uncommenting various parts will cause it to leak: // ---- BEGIN CODE ---------------------------------------------------- #include <boost/locale.hpp> #include <unicode/uclean.h> #include <iostream> using namespace boost::locale; using namespace std; int main() { generator gen; gen.categories( convert_facet | //collation_facet | // Various errors. //formatting_facet | // Various errors. //parsing_facet | // Various errors. message_facet | //codepage_facet | // Various errors. boundary_facet | calendar_facet | information_facet); locale newLoc = gen("zh_CN.GB18030"); locale::global(newLoc); cout.imbue(newLoc); // ios_info::get doesn't clean up after itself. //cout << as::date << time(0) << endl; // Do this at the end of the program to clean up resources. locale::global(std::locale("C")); cout.imbue(std::locale("C")); u_cleanup(); } // ---- END CODE ------------------------------------------------------ Dumping this as 'hello.cpp' and running this is how I'm debugging it: g++ hello.cpp -lboost_locale -licuuc && valgrind --leak-check=full --show-reachable=yes ./a.out Thanks, Jookia.
