Can you try applying the technique for debugging crashes in GC that is
outlined in etc/DEBUG?

In this frame, what does "info address from" say? If it says that
`from' is stored in some register, can you display the value of that
register, and using that value reproduce what is from->string?
And which Emacs version is that: 24.0.93 or 24.0.94?
