I haven't backported that patch yet but as far as I can see the infinite loop
can't be triggered with the following patches applied:
```
afd19a71 libdwfl: Handle unaligned Phdr in dwfl_segment_report_module
cf41ae95 libdwfl: Handle unaligned Ehdr in dwfl_segment_report_module
7f5e5da8 libdwfl: Make sure note data is properly aligned.
```

I've just ran into that as well. I'll apply the patch and report back if it's
still there.
