They say that it is ok, because this is the responsibility of the dynamic loader. (see this discussion if you're interested https://github.com/golang/go/issues/28909)

You should file a bug report against musl-libc.  If it doesn't support
.init_array in a shared object,
it is pretty much broken and shouldn't be used at all.
