Thanks for the report. You can most likely work around this by changing the function name "and" to something else, like "myand": bool and(int x, int y) { return mod(float(x), exp2(float(y))) != 0.0; } The fix will be shipped in a future update. *** This bug has been marked as a duplicate of bug 229378 ***
