Hellos, I recently upgraded to vs2012 and am making liberal use of its leak detection described here: http://msdn.microsoft.com/en-us/library/x98tx3cf.aspx However, I'm running into a spot of trouble. I rely on the C++ style new commands to allocate memory and as such, I make use of redefining this call in order to get a specific file and line, at the end of my programs execution, to where I allocated memory which is leaking. It's super effective! According to the link above, the new command is to be redefined thusly: #ifdef _DEBUG #ifndef DBG_NEW #define DBG_NEW new ( _NORMAL_BLOCK , __FILE__ , __LINE__ ) #define new DBG_NEW #endif #endif // _DEBUG However, boost no likey. I get a syntax error in 'initializer.hpp' at the following line (122) of code: new(dest) value_T( boost::detail::variant::move(operand) ); ... saying it no longer knows what 'dest' is. A bit puzzling to be honest. I'm no C++ artisan, so I'm a bit stumped as to how I should elegantly avoid this issue. I really don't need boost to use this redefined new, as I'm sure it's as leak proof as can be, but I'm not sure if it's possible to somehow define my way out of that jam? Or perhaps change the definition so that the line no longer results in a syntax error. Any ideas? Regards, Lasse
