Compiling python3.4 for use with valgrind. What else is needed?

Looking at existing stackoverflow answers, there are four things recommended to use valgrind to debug python memory leaks.

./configure

using:

• --with-pydebug
  
  
• --without-pymalloc
  
  
• --with-valgrind
  
  

It is also recommended to use SO and README.valgrind to use a suppression file to suppress some valgrind errors.

I'm interested in:

• Does the new parameter --with-valgrind
  
  make this suppression file necessary?

• The option --with-valgrind
  
  eliminates the need for --without-pymalloc
  
  ?

Answers I have read:

• use 3 options. / configure
• use suppression file
• - option -valgrind is new
