--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Thanks.
So, can you for that sort.i do -da -fdump-tree-all when compiled both with
stage1 and stage2 and see where things start to differ?
Or, try to change either:
STAGE1_TFLAGS += -fno-checking
STAGE2_CFLAGS += -fno-checking
STAGE2_TFLAGS += -fno-checking
in toplevel Makefile.in to -fchecking=1 or
STAGE3_CFLAGS += -fchecking=1
STAGE3_TFLAGS += -fchecking=1
after it to -fno-checking and see if the comparison failures go away.  That
would verify your -fno-checking idea.  If that proves to be true, where
sort.i.* starts to differ could hint on what TU from stage1 or stage2 could be
rebuilt with -fno-checking or -fchecking=1 to see if the difference goes away. 
Or do a binary search among *.o files.
Sorry I can't help more, but this really isn't debuggable with cross-compilers.
