Hi Jonas,

If I remember correctly, this mono_debug_open_image_from_memory()
function was requested by someone who wanted to embed Mono a long time
ago, but I don't remember ever getting any feedback about it or anyone
actually using it.

We should now, that we have an actual customer for it, look at properly
testing fixing the implementation.
