+    nss: Group merge does not react to ERANGE during merge (bug 33361)
+    
+    The break statement in CHECK_MERGE is expected to exit the surrounding
+    while loop, not the do-while loop with in the macro.  Remove the
+    do-while loop from the macro.  It is not needed to turn the macro
+    expansion into a single statement due to the way CHECK_MERGE is used
+    (and the statement expression would cover this anyway).
