Unfortunately, I didn't have time to look into the details of this
issue.  As I understood your comment, it is not a FP in the tests but
rather an issue in copy.c on these platforms.
I'm fine with the proposed patch for the time being, i.e. to NOP out
some test cases to avoid FPs- but it then would probably make sense
to document the varying behavior, at least in a FIXME in the test.

Thanks & have a nice day,
