[Bug binutils/10341] New: objdump segfault on stripped elf files

[svenpeter at gmail dot com]

arm-eabi-objdump segfaults when you try to disassemble a stripped elf file on
mac os. this bug does not happen on linux.
It is easily reproduceable given that you have any arbitrary ELF file:
armeb-eabi-strip --strip-all file.elf && armeb-eabi-objdump -d file.elf

Disassembly of section .text:

02380000 <.text>:
