Update.
2001-12-06 Ulrich Drepper <drepper@redhat.com> * libio/vasprintf.c (_IO_vasprintf): Free buffer on failure. * assert/assert.c: Check result of __asprintf call and don't use string if it failed. * assert/assert-perr.c: Likewise. * inet/rcmd.c: Likewise. * locale/programs/localedef.c (main): Check result of construct_output_path and exit if it failed. (construct_output_path): Check result of asprintf and mkdir calls and fail if they failed. * posix/getopt.c: Check result of __asprintf calls and fail if they failed. Patch by Dmitry V. Levin <ldv@alt-linux.org>.
