Patch and tests work for me.  Uploaded a patch that is identical except
the file paths are fixed.

Was the old behavior stable across compilers anyway?  It memcmpared two
different structs and IIRC only the first item of each struct is
guaranteed to be at the start of the memory location.  No?

With this patch only same-struct objects are memcmpared.
