Should be
if (_capa < 1)
_capa = 1;
in constructor?

It can be, I did this in case _capa=-1 means uninitialized where _capa = 0 is an error

Why not declaring size here?

The value needs to be computed before the realloc to avoid use after free

Hello !
Charles a fait des corrections parce que son compilateur a un peu plus de warnings que nous.
Il a fait une pull request pour ces modifs :
https://github.com/micmacIGN/micmac/pull/197/files
Dans incr_capa() il a rajouté un test de _capa==0 et mise à 1 pour éviter les accidents. (Je ne sais pas quel message le compilateur lui a dit pour remarquer le problème).
Je propose juste de passer ce test dans le constructeur parce que autant régler le pb tout de suite ?

Please check back later.
Mostly "maybe uninitialized" variable making the compilator not happy and use of pointer arithmetic with freed pointer which trigger compilation warning/error.
Need to check if graph cut reallocation code still used. If yes need to insure that the old freed pointer not used to suppress the compilation error.
Maybe others compiler will trigger other errors.
