Bug ID: 43370
Summary: Clang crashes in code generation of builtin atomic
operation.
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org

clang crashes during the compilation of a test program
compiled using command : clang test.cpp
---------------------------------------
// test.cpp
typedef unsigned long long uint64_t;
template<int UNUSED>
void fun()
{
uint64_t v[2];
__atomic_store_n(v, 0, 0);
}
int main()
{
fun<3>();
}
