I think I found two related bugs, steps to reproduce will be more clear than
a description:
It is present in stable 2.20.1 and using latest git snapshot, and using any device/file as disk, using here a loop dev with a backing file of 256MiB
just for example.
Fixed. Thank you for the report.

Thank you!

I will test it in few hours ;)

Works fine (default value after out-of-range) :)

Still remains the other bug that does not allow to specify "last sector" that just fits the size in +sectors/+N(K|M|G).

Example:

Command (m for help): n
Partition type:
   p   primary (0 primary, 0 extended, 4 free)
   e   extended
Select (default p):
Using default response p
Partition number (1-4, default 1):
Using default value 1
First sector (2048-524287, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-524287, default 524287): +255M
Value out of range.
Last sector, +sectors or +size{K,M,G} (2048-524287, default 524287): +261120K
Value out of range.
Last sector, +sectors or +size{K,M,G} (2048-524287, default 524287): +522240
Value out of range.
Last sector, +sectors or +size{K,M,G} (2048-524287, default 524287): +522239
Partition 1 of type Linux and of size 255 MiB is set

Command (m for help): p
