With DMD 2.052 this gives some access violations:


import std.range, std.algorithm;
void main() {
    auto range1 = iota(0.0, 5.0, 1.0);
    double foo(double x){ return 1.0; };
    auto foor = map!foo(range1);
    foreach (x; foor) {} // OK

    auto range2 = iota(1, 5, 1);
    int bar(int x){ return 1; };
    auto barr = map!bar(range2);
    foreach (x; barr) {} // OK

    float delegate(float) spam1 = (float x){ return 1.0f; };
    auto spamr1 = map!spam1(range1);
    foreach (x; spamr1) {} // object.Error: Access Violation

    double delegate(double) spam2 = (double x){ return 1.0; };
    auto spamr2 = map!spam1(range1);
    foreach (x; spamr2) {} // object.Error: Access Violation

    real delegate(real) spam3 = (real x){ return 1.0L; };
    auto spamr3 = map!spam3(range1);
    foreach (x; spamr3) {} // object.Error: Access Violation
}
