+    iconv: iconv -o should not create executable files (bug 33164)
+    
+    The mistake is that open must use 0666 to pick up the umask,
+    and not 0777 (which is required by mkdir).
+    
+    Fixes commit 8ef3cff9d1ceafe369f982d980678d749fb93bd2
+    ("iconv: Support in-place conversions (bug 10460, bug 32033)").
