Compiling python3.4 for use with valgrind. What is still necessary?

Question

Looking at existing stackoverflow answers, there are 4 things recommended for using valgrind to debug python memory leaks.

./configure using:

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

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

I'm wondering:

1. Does the newer --with-valgrind option eliminate the need for this suppression file?

2. Does the --with-valgrind option eliminate the need for the --without-pymalloc?

Answers I've read:

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