<pre>I did compile the following program with "clang++ -fopenmp -std=c++14 test.cpp"
using a trunk build from a few days ago:
#include <cstdlib>
#include <functional>
#include <memory>
struct A {
A() : ptr(nullptr, free) {}
A& operator=(A&&) = default;
std::unique_ptr<void, std::function<void(void*)>> ptr;
};
int main() {
A test;
#pragma omp declare reduction(+ : A : omp_out) initializer(omp_priv = A())
#pragma omp parallel reduction(+ : test)
{}
return 0;
}
Running it results in a segmentation fault. I'm a little worried that this
could be a user error :/, sorry if this is the case.
GCC reports a missing copy constructor, the Intel compiler version runs.</pre>
