wiki example doesn't work with master branch

[Blopeur]

Hi,
I am trying to run the wiki example and while i can do basic jit operations ( even basic custom matrix code for the sake of it)
I am having an issue when passing the type. I am using the wiki example :

#include <iostream>

struct F {
  int i;
  double d;
};

template <typename T, int S>
struct G {
  T arr[S];
};

template <typename T>
[[clang::jit]] void run() {
  std::cout << "I was compiled at runtime, sizeof(T) = " << sizeof(T) << "\n";
}

int main(int argc, char *argv[]) {
  std::string t(argv[1]);
  run<t>();
}

When i run i get the following error :

./jit-t "double"
Declaration may not be in a Comdat!
void (i8*)* @__clang_call_terminate
in function __clang_call_terminate
LLVM ERROR: Broken function found, compilation aborted!

I have tried to pass the type in another custom examples and I hit the same error every time ?

Am I missing something?

Also, i saw in the issues that there is a new [[clang::for_dynamic_instantiation]] API in 9.0-ni branch. Any pointer to updated documentation can be helpful.

Update :

the issue seems strange , the following code works :

#include <iostream>
using namespace std;
struct F {
    int i;
    double d;
};

template <typename T, int S>
struct G {
    T arr[S];
};

template <typename T>
[[clang::jit]] void run() {
    std::cout << "I was compiled at runtime, sizeof(T) = " << sizeof(T) << "\n";
}

int main(int argc, char *argv[]) {
    run<"double">();
}

if I use the very basic example and add a single line : creating a string in main , even without using the string for anything the jit process fail

#include <iostream>
#include <cstdlib>

template <int x>
[[clang::jit]] void run() {
  int z = 0;
  for (int i = 0 ; i < x ; i++){
    z = x + 5 * x;
  }
  std::cout << "I was compiled at runtime, x = " << x <<  " z = " << z << "\n";
}

int main(int argc, char *argv[]) {
  int a = std::atoi(argv[1]);
  std::string t("double");
  run<a>();
}

Same error .. looks like allocating a string is what trigger the issue ..
