As seen in scylladb/scylladb#11420,
we don't support decoding backtraces in the following format:

                                                           #0  0x00007fd2dab662a2 raise (libc.so.6 + 0x3d2a2)

```
    scylladb#1  0x00007fd2dab4f950 abort (libc.so.6 + 0x26950)
```

Fixes scylladb#1206
