+            A bug which could cause compiled programs to loop forever
+            when glibc's iconv implementation (gconv) wasn't available
+            has been fixed, so these programs will now terminate with
+            an error. As a result of this change, however, GHC
+            compiled programs now also specifically recognize ASCII
+            encodings, and can bypass iconv in these cases. This
+            allows statically compiled programs to exist inside an
+            initramfs, for example. (issues #10298, #7695).
