prove that man-db and tar works(which used to segfault). hope builtin argp
could be updated soon. i will report if i met another NULL pointer case.
thanks for your work! :)

Hi,

Likewise the LI18NUX 2000 specification (p. 39) says
"The msgid argument is a null-terminated string."
And likewise the LSB
since my libc is musl, tar is using builtin argp implementation, which will
pass NULL as msgid to dgettext without additional checks.
but according to
https://www.gnu.org/software/gettext/manual/html_node/Interface-to-gettext.html,
passing NULL to gettext is undefined. and, musl chose to crash..
