--- Comment #3 from zhouyan at me dot com ---
Here is version that shall be thread-safe, that produce the same problem,
#include <random>
int main ()
{
_Cilk_for (int i = 0; i != 10000; ++i) {
std::mt19937 eng(i);
std::normal_distribution<> rnorm;
rnorm(eng);
}
}
The original program which I first found the issue was thread-safe. The MWE I
first submitted was created a little too hasty. In fact, neither mt19937 nor
normal_distribution is thread-safe. Anyway, I don't think race condition was
the problem.
