Subject: [PATCH] Properly run tst-spawn5 directly [BZ #28067]
Date: Fri, 9 Jul 2021 06:04:08 -0700 [thread overview]
Message-ID: <20210709130408.1620161-1-hjl.tools@gmail.com> (raw)
Change tst-spawn5.c to handle tst-spawn5 without optional path to ld.so,
--library-path nor the library path when glibc is configured with
--enable-hardcoded-path-in-tests. This fixes BZ #28067.
