Bug ID: 19517
Summary: Unexpected template recursion limit hit for constexpr
function template
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
The sample code below causes a fatal error.
========================================
template<typename T>
constexpr T f(T const&);
template<typename T>
constexpr T g(T const& val) {
return val >= 10 ? val : f(val + 1);
}
template<typename T>
constexpr T f(T const& val) {
return g(val);
}
int main() {
return f(0);
}
========================================
I think that this code should be compiled successfully.
Note that this code is compiled successfully if these functions are not
constexpr function.
(e.g. removing "constexpr" specifier from the function g)
I suspect that this is caused by bug 16008.
