Hi Alec,
Please could you try the uploaded patch.
The problem is that the binary you have is corrupt. The e_shstrndx field in
the ELF header is wrong. It says that the string table is held in section 8,
but there is no section 8 in the object file!
The patch updates the BFD library so that it can cope more gracefully with
this sort of broken binary, and it also updates readelf to detect this kind of
error and report it to the user. With the patch applied I get this result from
running "objdump -p" on your test file:
BFD: warning: C3640-IS.BIN has a corrupt string table index - ignoring
C3640-IS.BIN: file format elf32-big
Program Header:
LOAD off 0x000000f4 vaddr 0x80008000 paddr 0x80008000 align 2**7
filesz 0x00d7e8e0 memsz 0x00e664c0 flags rwx
and this result from running "readelf -h -S":
ELF Header:

Section header string table index: 8 <corrupt: out of range>
Section Headers:

[ 3] <no-name> PROGBITS 80d7fd20 d77e14 006bc0
Note - do you know what type of architecture the 0x1e value in the e_machine
field of the ELF header represents ? If so we could add it to the list of known
values so that readelf can identify it.
Cheers
Nick
