commit 911ec6411821bda535d09778df7503b92f0eafab
Author: dtucker at openbsd.org <dtucker at openbsd.org>

    upstream: Allow for different (but POSIX compliant) behaviour of
    basename(3) and prevent a use-after-free in that case in the new sftp-compat
    POSIX allows basename(3) to either return a pointer to static storage
    or modify the passed string and return a pointer to that.  OpenBSD does
    the former and works as is, but on other platforms "filename" points
    into "tmp" which was just freed.  This makes the freeing of tmp
    consistent with the other variable in the loop.
    Pinpointed by the -portable Valgrind regress test.  ok djm@ deraadt@
