[minicoredumper] gdb corrupt stack

[Marco.Felsch at preh.de]

Hi,

I had cross compiled the minicoredumper for the aarch64.
Generating the core file works fine but analyze the the core file with gdb on a remote host isn't possible.

I only want a small core file to show the backtrace within gdb.
I am able to show the top most (#0/#1) backtrace entries but no more.

My setup was:
- cross compiler: gcc-linaro-6.2.1-2016.11-x86_64_aarch64-linux-gnu
- cross compiled elfutils-0.169, and json-c lib
- my gdb sysroot contains all the libraries and the executable

Maybe I forgot to set a specific configuration?
You will find the generic.recept and the gdb output attached.

My config file:
{
    "stacks": {
        "dump_stacks": true,
        "first_thread_only": false,
        "max_stack_size": 0
    },
    "maps": {
        "dump_by_name": [
            "[vdso]"
        ]
    },
    "compression": {
        "compressor": "gzip",
        "extension": "gz",
        "in_tar": true
    },
    "dump_auxv_so_list": true,
    "dump_pthread_list": true,
    "dump_robust_mutex_list": true,
    "live_dumper": false,
    "write_proc_info": false,
    "write_debug_log": false,
    "dump_fat_core": true
}

gdb-output:
