Thank IOHannes for pointing me to valgrind.  From a preliminary test I didn't see any memory leaks with Memcheck.  

  I used the command line: valgrind —leak-check=yes pd-extended myPatch.pd

  Valgrind only returned "Conditional jump or move depends on uninitialised value(s)" for various processes in the Mac OS and Pd

  I also tried Memcheck on my own code using a dummy program and get no leaks.  

  Maybe I'm not using valgrind correctly to test a .pd file?
