+    Test stdlib/test-bz22786 exits now with unsupported if malloc fails.
+    
+    The test tries to allocate more than 2^31 bytes which will always fail on s390
+    as it has maximum 2^31bit of memory.
+    Before commit 6c3a8a9d868a8deddf0d6dcc785b6d120de90523, this test returned
+    unsupported if malloc fails.  This patch re enables this behaviour.
+    
+    Furthermore support_delete_temp_files() failed to remove the temp directory
+    in this case as it is not empty due to the created symlink.
+    Thus the creation of the symlink is moved behind malloc.

+    ChangeLog:
+    
+            * stdlib/test-bz22786.c (do_test): Return EXIT_UNSUPPORTED
+            if malloc fails.
