[Bug binutils/6774] New: objcopy gives "assertion failed" when extracting symbols from ELF executables linked with "--emit-relocs"

[stefan dot bucur at gmail dot com]

It seems that when asked to extract symbols, objcopy cannot process ELF
executables that were built with the "--emit-reloc" linker option. objcopy gives
an "assertion failed" and exits. The error and the procedure used to generate it
is as follows:

1. Create a very simple C program, test.c:

#include <stdio.h>

int main(int argc, char **argv) {
        return 0;
}

2. Build it with relocation information kept in the final executable:

$ gcc -o test -Wl,--emit-relocs test.c

3. Try to extract the symbols in a separate file:

$ objcopy --extract-symbol test test_sym
BFD: BFD (GNU Binutils for Ubuntu) 2.18.0.20080103 assertion fail
../../bfd/elf.c:5517
