Seems like some sort of tools problem. Have you tried generating a linker
map? Perhaps do an objdump --section-headers on the relevant intermediate
object files (i.e. .o files) to see if any of them have odd alignment
constraints or sizes. If so, try examining the assembly version of the
affected files to see how it is coming about.
