6 years ago I wouldn't call oat a "normal" ELF file. It is an ELF wrapper around Android bytecode :-)
Also, readelf just seems to parse it correctly, but it throws a warning:
$ readelf --dyn-syms b.oat
Symbol table '.dynsym' contains 4 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND readelf: b.oat: Warning: local symbol 0 found at index >= .dynsym's sh_info value of 0 1: 00001000 0x1f000 OBJECT GLOBAL DEFAULT 4 oatdata 2: 00020000 92884 OBJECT GLOBAL DEFAULT 5 oatexec 3: 00036ad0 4 OBJECT GLOBAL DEFAULT 5 oatlastword
I guess that is where it could have gone wrong.
Hello, while i've been using angr which depends on cle and cle on pyelftools i stumbled upon some weird errors regarding pyelftools.
I've tried to parse a simple .oat file which basically is normal ARM-32 elffile. Readelf parses it correctly. The following stacktrace is given:
`... /home/andy/angr/angr-dev/cle/cle/backends/elf.pyc in __register_dyn(self, seg_readelf) 341 Parse the dynamic section for dynamically linked objects. 342 """ --> 343 for tag in seg_readelf.iter_tags(): 344 # Create a dictionary, self.dynamic, mapping DT* strings to their values 345 tagstr = self.arch.translate_dynamic_tag(tag.entry.d_tag)

Hope you can fix this issue, Greetings
