http://d.puremagic.com/issues/show_bug.cgi?id=4246 Summary: Delegate literals passed to variadic templates function incorrectly Product: D Version: future Platform: Other OS/Version: Windows Status: NEW Keywords: wrong-code Severity: normal Priority: P3 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: sandford jhu.edu I found this while playing with delegate literals and map. Thankfully, map and non-variadic templates don't compile with delegate literals, but this example does: import std.stdio: writeln; import std.range; import std.algorithm; template bar(fun...) { auto bar(int[] r) { return fun[0](r.front); } } void main(string[] args) { int[] x = [1,2,3,4,5]; int y = 6; auto dg = (int t){ return t + y; }; auto list = bar!( dg )(x); auto list2 = bar!( (int t){ return t + y; } )(x); writeln(list,'\t',list2); return; } This prints out the correct value (7) when a delegate is passed in, but the delegate literal call results in a random printed number. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
