Not on my libc5-only machine (where I developed the code). We'll need to
get a reproducible case to be able to track it down. I'm guessing that
we are seeing float->int rounding problems, though I don't know why this
test query should show different results for the two columns.

What glibc2, compiler, and optimization level are you using? If you are
using anything above -O2 try backing down to that; if you are already
there then try -O0 and tell us what changes.
