+=item Out of memory
+
+On some systems, particularly those with smaller amounts of RAM, some
+of the tests in t/op/pat.t may fail with an "Out of memory" message.
+Specifically, in perl5.004_64, tests 74 and 78 have been reported to
+fail on some systems.  On my SparcStation IPC with 8 MB of RAM, test 78
+will fail if the system is running any other significant tasks at the
+same time.
+
+Try stopping other jobs on the system and then running the test by itself:
+
+       cd t; ./perl op/pat.t
+
+to see if you have any better luck.  If your perl still fails this
+test, it does not necessarily mean you have a broken perl.  This test
+tries to exercise the regular expression subsystem quite thoroughly,
+and may well be far more demanding than your normal usage.
+
+You may also be able to reduce perl's memory usage by using some of
+the ideas described above in L<"Malloc Performance Flags">.
