为什么valgrind的DRD工具抱怨“线程加载冲突…大小为4”:关于这样的代码:
- void SomeFunction(const int& value)
- {
- boost::bind(...,value); /* <-- complaines on this line
- with last backtrace function "new(int)" */
- }
boost :: bind()是否按引用或值存储值?
解决方法
按价值.

但你可以改为copy by ref:
- void SomeFunction(const int& value)
- {
- boost::bind(...,boost::ref(value));
- boost::bind(...,boost::cref(value)); // by const ref
- }

a copy of the value of i is stored into the function object. boost::ref and boost::cref can be used to make the function object store a reference to an object,rather than a copy:
int i = 5;bind(f,ref(i),_1);
bind(f,cref(42),_1);
