Bug ID: 49148
Summary: Default template parameter value from
brace-initialization
Product: clang
Version: 11.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: tom...@gmail.com
CC: blitzrak...@gmail.com, dgre...@apple.com,

Clang does not allow brace-initialization in default value of template
parameter. I hope I used the right terminology.
Example:
template <int I = {}> void foo(int i = {});
error: expected expression
Default value of the function parameter is accepted, but the template one is
not.
I did not figure out whether this is covered in the standard, however I think
that the current state is inconsistent (is it alright for function, but not for
template).
(Works in GCC.)
