Bug ID: 15390
Summary: default arguments should be allowed only in function
declaration
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Clang accepts this code without a error.
void (*k(int a))(int b = 5);
According to standard:
[dcl.fct.default]p3 A default argument shall be specified only in the
parameter-declaration-clause of a function declaration or in a
template-parameter.
[dcl.dcl]p7 If the decl-specifier-seq contains no typedef specifier, the
declaration is called a function declaration if the type associated with the
name is a function type.
I'm not sure if this wording prohibits the code above. But I believe this
default argument is incorrect.
