No, because I think the sense is reverted:

+    check {
+      type: INT_32
+      minval: 0
+      maxval: 3
+      env_alias: MALLOC_CHECK_
+      secure_env_alias: true
+    }

That's why I said you need to document what the options are and what 
they do in AT_SECURE mode, and the default value.

Thanks,
Florian
