            Bug ID: 25031
           Summary: nm reports wrong address on 32bit
           Product: binutils
           Version: 2.34 (HEAD)
            Status: UNCONFIRMED
          Severity: normal

         Component: binutils
          Assignee: unassigned at sourceware dot org

example

This happens since binutils 2.32.51.20190611 (The Debian version mostly tracks
svn)
and it was working on 2.32-8 (updated to 20190424)

to reproduce:
nm elfmix1.not_a
nm: 42-Mach-O.o: file format not recognized
nm: 43-Mach-O.o: file format not recognized
nm: Mach-O.o: file format not recognized

return42_or_3_long_name.o:
0000000000000000 T return42_or_3
nm: return42_or_3_long_name.c: file format not recognized
nm: regen_elfmix.sh: file format not recognized

return42_or_3_long_name.obj:
ffa49ce800000000 T return42_or_3


before, with old binutils it was printed correctly
 nm elfmix1.not_a
nm: 42-Mach-O.o: file format not recognized
nm: 43-Mach-O.o: file format not recognized
nm: Mach-O.o: file format not recognized

return42_or_3_long_name.o:
0000000000000000 T return42_or_3
nm: return42_or_3_long_name.c: file format not recognized
nm: regen_elfmix.sh: file format not recognized

return42_or_3_long_name.obj:
00000000 T return42_or_3


Looks like the returned output is half full of uninitialized values


on amd64 it works correctly

nm elfmix1.not_a 
nm: 42-Mach-O.o: file format not recognized
nm: 43-Mach-O.o: file format not recognized
nm: Mach-O.o: file format not recognized

return42_or_3_long_name.o:
0000000000000000 T return42_or_3
nm: return42_or_3_long_name.c: file format not recognized
nm: regen_elfmix.sh: file format not recognized

return42_or_3_long_name.obj:
0000000000000000 T return42_or_3
