52925 does not exists. You mean PR50925 ?
These bugs are hard to fix and open since over 2 years now, see PR42204
You might get around these by building with -fno-caller-saves which avoids the
spill fails in some situations. I don't know if someone is working on these
issues. AVR with its register layout is real stress test for the register
allocator, but AVR is neither primary nor secondary platform so that such bugs
are outside the focus of GCC developers.
