------- Comment #9 from clugd...@yahoo.com.au 2009-04-09 04:24 -------
Error messages generated from my patch for the code below:
bug.d(2): Error: static assert (0) is false
bug.d(9): instantiatied from here: bar!()
bug.d(14): 100 recursive instantiations from here: foo!(196)
bug.d(19): 253 recursive instantiations from here: baz!(300)
(Oops -- just realised I there's a typo in "instantiated" in the non-recursive
messages. That's easy to fix).
Note that it detects the recursive instantiation in foo!(), even though it is
instantiated from three different places.
--------
template bar() {
static assert(0);
}
template foo(int N) {
static if (N>0) {
static if (N&1) alias foo!(N-3) foo;
else alias foo!(N-1) foo;
} else alias bar!() foo;
}
template baz(int M) {
static if (M<50) {
alias foo!(M*4) baz;
} else alias baz!(M-1) baz;
}
void main() {
int x = baz!(300);
}
