value. * stdio-common/tst-fmemopen2.c (do_test): Avoid fmt string warning if off_t is different rank from size_t. * sysdeps/generic/unwind-dw2.c (extract_cie_info, execute_cfa_program, uw_frame_state_for): Avoid type punning warnings. * sysdeps/generic/unwind-dw2-fde-glibc.c (_Unwind_IteratePhdrCallback): Likewise. * sysdeps/generic/unwind-dw2-fde.c (_Unwind_Find_FDE): Likewise. (binary_search_single_encoding_fdes, binary_search_mixed_encoding_fdes, get_cie_encoding, linear_search_fdes): Don't mix char and unsigned char pointers.
