As reported here: https://github.com/openplanet-nl/issues/issues/45​

The following code causes an assertion failure:

enum Foo {
	A = (1 << 0),
	B = (1 << 1),
}
void Test(int f) {}
void Main() {
	Test(Foo::A = true | Foo::B);
}

The assertion hit is here: https://github.com/codecat/angelscript-mirror/blob/6888f245e61d7cd2728e7f3f0e088dcec4e22066/sdk/angelscript/source/as_compiler.cpp#L16282​

Obviously it is invalid syntax that doesn't really make sense, but the assertion probably shouldn't be thrown.

Thanks for reporting this. I'll look into it.

I've fixed this old bug now in revision 2822.

Andreas
