Bug ID: 43990
Summary: Incorrect error on static_assert expression
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: unassignedclangb...@nondot.org

Code to produce the issue described.
The C++11 code below produces a compilation error stating that the
static_assert expression is not an integral constant expression. GCC trunk
compiles this. Commenting-out the static assert removes the error.
template <typename T>
constexpr bool bar(T &) { return true; }
template <typename T>
constexpr bool foo(T &x) { static_assert(bar(x),""); return bar(x); }
int main(int argc, char *argv[])
{
int i;
constexpr bool x = foo(i);
return 0;
}
