Seems to work fine on i686-pc-linux-gnu. I would have guessed it to be
something related to padding, but it's weird that it's not seen in 32-bit mode.

On x86-64 using -m32 the size being passed to unformatted_write is 12. Its
aligning to nearest 32-bit boundary. Without -m32 size comes in at 16.
Both are long double which has different size on 32 vs 64 bit ma

I see. With that in mind, I think the patch for PR31915 that went in as r124741
is incorrect (and I share some of the blame since I approved it). We should use
the size argument the frontend provides to the unformatted_(r

Actually, there are two separate build subdirectories created under the arch
directory in the objdir. So on systems like mine, two separate libraries are
built.

The following simplistic patch solves this problem. Sometimes I think we get
overzealous with definitions and fancy configury. We all know the size is 10
bytes and 12 works.
This works:
Index: size_from_kind.c

Closing. Added the following comment to transfer.c:
/* Master function for unformatted writes. NOTE: For kind=10 the size is 16
bytes on 64 bit machines. The unused bytes are not initialized and never
us
