with a posix shell:

$ sh -c 'putc="printf \\"; ${putc}100'
@

but with yash:

$ yash -c 'putc="printf \\"; ${putc}100'
100

a workaround exist:

$ yash -c 'putc="printf \\\\"; ${putc}100'
@

but it breaks on other shells (it prints \100)

I'm using the version 2.36-1 included in Debian GNU/Linux 8 (jessie)

I discovered this bug developing a small shell library, where you can find an use case in the n_bytes_encode function of the lib/bytes.sh file included in http://www.trek.eu.org/devel/naive/naive-0.0.2.tar.gz

Thank you for the bug report, but I believe this bug has been fixed since version 2.38. Please try upgrading. If you think the bug is still unfixed in the latest version, which is 2.40, please reopen the bug report. Thanks!
