           Summary: std.range.chain and std.range.zip cannot get frame

          Platform: x86

import std.algorithm: map;
import std.range: chain, zip;
void main() {
    auto r = map!(x => 0)([1]);
    chain(r, r);
    zip(r, r);
}


DMD 2.061alpha gives:

...\dmd2\src\phobos\std\range.d(1988): Error: function
std.range.chain!(MapResult!(__lambda2, int[]),MapResult!(__lambda2,
int[])).chain.Result.save cannot get frame pointer to main
...\dmd2\src\phobos\std\range.d(1988): Error: function
std.range.chain!(MapResult!(__lambda2, int[]),MapResult!(__lambda2,
int[])).chain.Result.save cannot get frame pointer to main
...\dmd2\src\phobos\std\range.d(3792): Error: function
std.range.Zip!(MapResult!(__lambda2, int[]), MapResult!(__lambda2,
int[])).Zip.save cannot get frame pointer to main
...\dmd2\src\phobos\std\range.d(3792): Error: function
std.range.Zip!(MapResult!(__lambda2, int[]), MapResult!(__lambda2,
int[])).Zip.save cannot get frame pointer to main


This code compiles and runs correctly in DMD 2.060.

Additional problem: the error messages refer only to the locations inside chain
and zip, with no references to the call lines in main().
