+    Avoid fall-through in test-container if execlp fails.
+    
+    One of the implicit-fallthrough warnings from compiling glibc with
+    -Wextra appears to indicate an actual bug: the test-container code
+    could fall through inappropriately if execlp returns (which only
+    occurs on error).  This patch adds appropriate error handling in this
+    case to avoid that fall-through.
+    
+    Tested for x86_64.
+    
+            * support/test-container.c (recursive_remove): Use FAIL_EXIT1 if
+            execlp returns.
