Anyway, I wouldn't mind if the memset call in utility/value_init.hpp would become conditional, for example as follows:
#ifdef BOOST_VALUE_INITIALIZATION_NEEDS_MEMSET std::memset(&x, 0, sizeof(x)); #endif
Fernando (the author of value_init) mailed me that it's okay to him if I add an #ifdef like that to utility/value_init.hpp. Still I think it would be useful to have the issue officially reported. Aleksey, were you already planning to open a ticket on this issue? If so, please do! And please feel free to assign the ticket to niels_dekker :-) Of course, <boost/config/compiler/...> also needs to have BOOST_VALUE_INITIALIZATION_NEEDS_MEMSET added to various compiler versions: MSVC (all versions) Borland/Codegear build < 12.0.3140.16150 Sun (possibly all versions, I don't know exactly) GCC < 4.4.0
What do you think? And would it be okay to you to have such a macro, BOOST_VALUE_INITIALIZATION_NEEDS_MEMSET, defined in boost/config/compiler/, for those specific compiler versions?
