Sorry for annoying you again, but I really want to be sure we're talking about the same, as I cannot reproduce it with the latest version
Can you try this minimal code:
#include <SFML/Audio/Listener.hpp>
int main()
{
sf::Listener::setPosition(20.f, 0.f, 0.f);
}
You said you use the commit
c55b8c1, however the latest commit of branch 2.3.x has the SHA-1
0f1dc5a. The commit message is in both cases "Fixing #935: Secure function against random data return."
With that commit, the error output should be different than in your initial post. Can you show the new one?
Furthermore, which operating system, compiler and compiler version are you using? How are you linking SFML?
