I don't know about the specifics.  My supposition is that we may not
be copying the entire segment depending on where the map is placed.

This came up with respect to the GCC PCH implementation for parisc.  See
comments in host-hpux.h.  At the moment, we do have a PCH related bug.
See PR 39355.  While I know the problem is present in the PCH file, I
haven't been able to figure out how wrong data gets in the file.
