How exactly are you saving the state you want to load? The problem is that you can only load a saved state into the same executable as you used to save it. The ultimate reason for this restriction is that the saved state does not save any heap cells that are present in the executable but instead saves their (relative) addresses. loadState will raise an exception if the saved state does not match the executable.
By "silently crash" do you mean that it raises an exception that you are not handling or is this something else?

If I have a program I?d like to compile with polyc that looks like
fun main () = let val _ = PolyML.SaveState.loadState (hd (CommandLine.arguments())) in ? endwhat, if anything can I put in the ? and have it work?
All I really want is what is effectively a sequence of calls to ?use? in that slot, but there seem to be many ways of generating executables that silently crash.
