The longest a French Republic has lasted is 70 years. The fifth republic is today 66 years old. The ordinary can turn into the extraordinary in an afternoon.
No, De Gaulle created the V republic with a military coup [1]. There were troops all over France, including paratroopers in Fontainebleau at 60km from Paris [0], while the "président du conseil" of the 4th republic transmitted peacefully the power to De Gaulle, to mitigate a civil war.

"The May 1958 crisis (French: Crise de mai 1958), also known as the Algiers putsch or the coup of 13 May, was a political crisis in France during the turmoil of the Algerian War of Independence (1954–1962) which led to the collapse of the Fourth Republic and its replacement by the Fifth Republic led by Charles de Gaulle who returned to power after a twelve-year absence. It started as a political uprising in Algiers on 13 May 1958 and then became a military coup d'état led by a coalition headed by Algiers deputy and reserve airborne officer Pierre Lagaillarde, French Generals Raoul Salan, Edmond Jouhaud, Jean Gracieux, and Jacques Massu, and by Admiral Philippe Auboyneau, commander of the Mediterranean fleet. The coup was supported by former Algerian Governor General Jacques Soustelle and his activist allies.
The coup had as its aim to oppose the formation of Pierre Pflimlin's new government and to impose a change of policies in favor of the right-wing partisans of French Algeria."
When the military woke up again in 62 in Algiers, De Gaulle crushed them.
You got it reversed.
Additionally, during the 1958 coup itself he did basically give his support for it in the sense that he explicitly said he was "ready to assume the powers of the republic" if asked for (which is what the leaders of the coup demanded be done).
Massu, who had gained prominence and authority when he ruthlessly suppressed Algerian militants, famously declared that unless de Gaulle was returned to power, the French Army would openly revolt.

Because then, the coup was directed against him!
