Bug description

Currently, load_sha256 will fail the recursion detection when called through an imported macro where the context is not inherited/passed. This is because load_sha256 relies on an internal variable being passed around, which is lost in some cases.

load_sha256 should use an alternative recursion detection that does not rely on the context.
