Hello, For the following code: struct S { int a; float b; }; struct T { T(S s) {} }; int main() { T t(S{1, 0.1}); // ERROR HERE } gcc 4.6 trunk gives the following errors (with the --std=c++0x option): decl.cpp: In function 'int main()': decl.cpp:14:10: error: expected ')' before '{' token decl.cpp:14:10: error: a function-definition is not allowed here before '{' token decl.cpp:14:18: error: expected primary-expression before ')' token decl.cpp:14:18: error: expected ';' before ')' token It seems gcc is interpreting the statement as a function declaration. Is this the desired behaviour? Regards, Nate.
