bonjour,

je rencontre un comportement =C3=A9trange de la part de la fonction calcsiz=
e du module struct.

voici le probl=C3=A8me :
# 8<-----------
cd /tmp/
python --version
Python 3.10.1
python -m venv struct.test
source struct.test/bin/activate
python -c 'import struct; print(struct.calcsize("4sIQ4I2Q"), 4+4+8+(4*4)+(2=
*8))'
48 48
python -c 'import struct; print(struct.calcsize("4sIQ5I2Q"), 4+4+8+(5*4)+(2=
*8))'
56 52
python -c 'import struct; print(struct.calcsize("4sIQ6I2Q"), 4+4+8+(6*4)+(2=
*8))'
56 56
# 8<-----------

struct.calcsize("4sIQ5I2Q") ne retourne pas 52 comme attendu...

une explication ?

cordialement, lacsaP.
