I did some searching.

``__start_section`` and ``__stop_section`` are generated by the linker 
automatically for a given section.

I have been able to replicate what it should be doing using run.dlang.io.

```d
import std;
import core.attribute;

void main()
{
     writeln([var1, var2, var3], __start_sect_test, __stop_sect_test);
}

__gshared extern(C) extern {
     immutable int* __start_sect_test;
     immutable int* __stop_sect_test;
}

__gshared {
     @(ldc.attributes.section("sect_test"))
     int var1 = 72;
     @(ldc.attributes.section("sect_test"))
     int var2 = 43;
     @(ldc.attributes.section("sect_test"))
     int var3 = 59;
}
```

Now you'll have something to compare the ``__minfo`` symbols to.

One thing to check is that your triple is for the binary wasm otherwise 
it might not be using sections.
