Bug ID: 22278
Summary: terrible diagnostic for missing 'typename'
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
template<int N> struct Y { typedef int type; };
template<int N> void h() {
struct alignas(N) X {};
Y<alignof(X)>::type z;
}
gives:
<stdin>:4:4: error: expected ';' after expression
Y<alignof(X)>::type z;
^
;
<stdin>:4:23: error: use of undeclared identifier 'z'
Y<alignof(X)>::type z;
^
This is hopeless, and this is a really obvious case: we have a template-name
followed by a less-than.
Also note that we give a bogus fixit (why do we think a semicolon is a great
thing to insert before a '<'?), and don't recover as if the fixit is applied.
