I encounter the same kind of bug with 'git send-email'. Adding '--confirm=never' option to remove the confirmation prompt make it work.
The problem is on aarch64 too.

The ticket https://bugzilla.opensuse.org/show_bug.cgi?id=1120267 is the same thing for sure. The backtrace is the same. Another very simple example to reproduce:

```
perl -eprint\(\"42\\n\"\)\; # works
perl -deprint\(\"42\\n\"\)\; # fails when initializing readline
echo 'parse_options("ReadLine=0");' >> ~/.perldb
perl -deprint\(\"42\\n\"\)\; # works without readline support
```

Marking as dup.
