Hostname Option12 incorrect when hostname uses numbers only

[chrixxxi]

Hi, i am encountering an Issue with dhcpcd version 9.4.1 where i do start dhcpcd with the following command:
exec dhcpcd -B -K -4 -h "131313" eth0

The hostname in the Hostname Option 12, the value is '^T^T^T'.
I did try compiling dhcpcd with the hostname '141414' hardcoded to see if it could work and it does.

This seems to me like some kind of parsing error when creating the ifo struct.
Can anyone help me with this issue?

Thanks so much in advance.
Br,

Edit:
Did fix it by manipulating the hostname argument to: '-h ""131313""'

I'm unable to reproduce on my end.

The parsing for hostname is handled in if-options.c:L732. parse_str does handle double quotes (L264). Could you run dhcpcd in a debugger and breakpoint at if-options.c:737 (if you're on the master branch, that's where parse_str is called)? If you can reproduce this bug, let me know what value ifo->hostname shows after parse_str? (i.e., is it getting ^T^T^T or 131313 or something else?)

Please reopen if you can provide more details.
