stack trace for the sample program
When using a malformed raw string literal as a default argument to a member
function template, an internal compiler error occurs. LLVM installed from the
arch linux packages.
Here is a small example case, named test1.cpp and compiled with 'clang++
-std=c++11 test1.cpp' it produces the attached stacktrace:
#include <regex>
#include <string>
struct S {
template <typename T>
void foo(std::string s = R"\S+") {}
};
int main() { S{}.foo<int>(); }</pre>
