GLSL causes crash

[MOPO3OB]

Hello, this code crashes Pythonista app.

from scene import *

class Crash(Scene):
    def setup(self):
        self.shader = Shader('''
            int Zero() {
                return 0;
            }

            int zero = Zero(); // This line causes crash.

            void main(void) {}
        ''')

if __name__ == '__main__':
    run(Crash())

Still crashes in 311015. Will check later if it's Pythonista / iOS issue in Xcode.
