Bug ID: 24860
Summary: std::map::emplace calls wrong value type constructor
Product: libc++
Version: 3.6
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: ryancer...@gmail.com
CC: llvm-bugs@lists.llvm.org, mclow.li...@gmail.com
Classification: Unclassified
#include <string>
#include <map>
class Thing {
public:
Thing(const std::string &a) : mS(a) {};
private:
Thing(const Thing&) = delete;
Thing(Thing &&) = delete;
std::string mS;
};
int main(int argc, char *argv[]) {
std::map<int, Thing> m;
m.emplace(0, std::string("hello"));
}
This tries to call the deleted copy constructor instead of calling
Thing::Thing(const std::string &) to emplace the object in the std::map.
