Yes, there is something really weird going on at the interface between C and Ada. Unfortunately I don't seem to be able to reproduce on Linux. Could you see what object code has been generated for the line gcc_assert (Nkind (gnat_root) == N_Compilation_Unit); in stage1-gcc/ada/trans.o and prev-gcc/ada/trans.o?
