poc and full stack trace

Hello,

We are currently working on fuzz testing feature, and we found a *failed to
allocate* error on `objdump`.

The stack traces are as follow:
```

```
The full stack trace is attached.

**Step to reproduce**

We configured `objdump` using 

`CFLAGS="-g -O0 -fsanitize=address" ./configure --prefix=$(pwd)/
--disable-shared --enable-targets=all`

and built it using `make -j 10`, and run it with:

```
./objdump --disassembler-options=data16 --debugging-tags <attached file> -d
```

The input file is attached.

**Environment**
- OS: Ubuntu 18.04.5 LTS
- GCC version: gcc 7.5.0
- binutils version: commit (98ca73a) of master branch on sourceware git
