--- Comment #3 from Justin <mrjn...@gmail.com> ---
I ran into this myself when attempting compile a service that we've had in
production for more than a year after updating to DMD 2.083.0.  I was able to
create a small artificial repro case, runnable here:
https://run.dlang.io/is/ssx7CP


import std.algorithm;
import std.range;
void main()
{
    static struct Rec
    {
        int foo;   
    }
    auto results = [[1,2], [3,4]]
                       .map!(q => q.map!Rec.chunkBy!"a.foo")
                       .joiner;
}

This is definitely a regression as this code builds with DMD 2.080.1 and prior.
