Bug ID: 36728
Summary: Assertion failed: (!ParamType.hasQualifiers() &&
"non-type template parameter type cannot be
qualified")
Product: clang
Version: 6.0
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org
Reporter: brenton at wolfram.com
CC: dgregor at apple.com, llvm-bugs at lists.llvm.org
This triggers an assert in clang:
template <typename T, T const data[]>
struct helper {
static constexpr T value = helper<T, data>::value * data;
};
Assertion failed: (!ParamType.hasQualifiers() && "non-type template parameter
type cannot be qualified"), function CheckTemplateArgument, file
