What is the ruling of Islamic law regarding a fasting person who experiences an erection while talking to a woman?

The fasting person should avoid everything that incites their desires. Their eyes and ears should fast from the unlawful just as their stomach and private parts fast. It is stated in the Hadith Qudsi: "Fasting is for Me, and I reward for it. He gives up his desires, food, and drink for My sake." What was mentioned is not considered among the things that break the fast.
