python3's parser stack overflows on deeply-nested expressions, for example:

[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]

or

aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa()))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))

These are both minimal examples, so if you remove one level of nesting from either then python3 will behave normally.
