Looks similar to this #43 (comment)
Could you try it with v2.103.1?

[cyrusmsk]

I can confirm that my .proto file generated with ldc1.33, and didn't work with ldc 1.36

[cyrusmsk]

@dcarp Will it be possible to rewrite part of the code, that using chain(...).init.empty behavior? based on comments from the bugzilla that this is "undefined behavior" in the range API currently...

[cyrusmsk]

Maybe use?
import std.traits : isArray;
static if (isArray!(typeof(res)))
