D2 code:


import std.stdio, std.algorithm, std.range;
auto foo(int p) {
    return map!((int n){ return p; })(iota(3));
}
void main() {
    writeln(take(foo(2), 20));
}


To me it prints:
[4221068, 4221068, 4221068]

Do you know if this is a known bug/problem?

Bye,

The problem is the parameter p is not being heap allocated.  I'm fairly sure it's already in bugzilla, something about failing to detect escaping references with alias parameters.
