which would instrument Perl in memory, run Perl on test.pl,
then finally report any memory problems.

+
+Third Degree is a tool for memory leak detection and memory access checks.
+It is one of the many tools in the ATOM toolkit. The toolkit is only
+available on Tru64 (formerly known as Digital UNIX formerly known as
+DEC OSF/1).
+
+When building Perl, you must first run Configure with -Doptimize=-g
+and -Uusemymalloc flags, after that you can use the make targets
+
+"perl.third" and "test.third". The short story is that with "atom"
+you can instrument the Perl executable to create a new executable
+called "perl.third." When the instrumented executable is run, it
+creates a log of dubious memory traffic in file called "perl.3log".
+See man atom and man third for more information. The most extensive
+Third Degree documentation is available in the Compaq "Tru64 UNIX
+Programmer's Guide", chapter "Debugging Programs with Third Degree".
