Because you can run o32 binaries on hardware with 64-bit registers,
and there are some ugly corner cases where the upper half of registers
can cause problems - e.g. for things which have undefined behavior if
the input registers are not correctly sign extended. You've probably
built a 32-bit kernel for a processor that GDB knows is actually
64-bit. But if your debug agent only supplies 32 bits, then GDB will
get along fine (once it knows that).
If you don't want to change GDB versions, an appropriate "set arch"
might work - but I recommend the current snapshots.
