The size of the device is 268435456 bytes,
+255M is relative to the begin of the partition, it means
(2048 * 512) + (255 * 1024 * 1024) = 268435456 bytes
Right.
but the begin of the last sector (in bytes) is
268435456 - 512 = 268434944 bytes (LBA sector 524287)
Right?
Right.
From [2048, 524287] (all inclusive), so
(524287 - 2048 + 1) * 512 = 522240 and 522240 * 512 / 2**20 = 255
Indeed, when you say, for example, these sizes: p1 = +55M, p2 = +100M,
and now try to set +100M to p3, is not posible, so accept the default
value, and you can see that the size is equal to p2, that is right.
So the issue appears when last sector is specified in +sectors or
+size(K|M|G), only
