+Subject: [PATCH] ch-misc: Do not check errno in realpath_ unless realpath
+ returns NULL
+Bug: https://github.com/hpc/charliecloud/pull/1550
+
+glibc's realpath may set errno also on success, as POSIX specifies
+errno should only be checked after realpath if the return value is not NULL.
+
+See for example:
