Summary: Incorrectly building an initializer for every union
member
Product: clang
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++0x
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
clang tries to create an implicit initializer for every member of a union:
$ cat union.cpp
struct S { S(char); };
union U {
S s; int n;
U() : n(0) {}
};
$ clang++ -std=c++0x union.cpp
union.cpp:5:3: error: constructor for 'U' must explicitly initialize the member
's' which does not have a default constructor
U() : n(0) {}
^
union.cpp:4:5: note: member is declared here
S s; int n;
^
union.cpp:1:8: note: 'S' declared here
struct S { S(char); };
^
