Bug 85 – Array of classes doesn't function as array of interfaces

Testcase below - originally posted as a comment in Bug 65. Note that while this can be worked around simply by changing the Class[] to I[], the code as it is below generates an incorrect program. ------------------ interface I { I[] foo(); uint x(); } class Class : I { I[] foo() { // changing this to I[] f = new Class[1] fixes the bug Class[] f = new Class[1]; f[0] = new Class; return f; } uint x() { return 0; } } void main() { Class c = new Class(); assert (c.x == 0); assert (c.foo[0].x == 0); } ------------------
