Subject: [PATCH] rc-misc.c: Allocate memory for 'file'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is a partial revert of commit 8e02406d ("rc-misc.c: remove
references to PATH_MAX"), which changed 'file' to a null pointer with no
associated storage.

../openrc-0.44.10/src/rc/rc-misc.c: In function ‘_rc_deptree_load’:
../openrc-0.44.10/src/rc/rc-misc.c:392:33: warning: ‘%s’ directive argument is null [-Wformat-overflow=]
392 |                                 eerror("Clock skew detected with `%s'", file);
    |                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fixes: 8e02406d ("rc-misc.c: remove references to PATH_MAX")
Closes: #493
