Subject: [PATCH] gnulib/argp-help: Fix dereference of a possibly NULL state
|
|
|
80913e |
|
|
|
80913e |
All other instances of call to __argp_failure() where there is
|
|
|
80913e |
a dgettext() call is first checking whether state is NULL before
|
|
|
80913e |
attempting to dereference it to get the root_argp->argp_domain.
|
|
|
