Looks similar to this https://github.com/dcarp/protobuf-d/issues/43#issuecomment-1767278229 Could you try it with v2.103.1?

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

cyrusmsk commented 4 months ago

@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 commented 4 months ago

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