>Description:
Use FreeBSD-BETA3 iso to boot, select "Live CD" to enter into the live filesystem.
then run: fdisk -i ad0 

first time: input a invalid decimal number when prompt to enter the size of slice.
second time:input a valid decimal number

Two times within one fdisk invocation.

It's erroneous to determine the size of the slice according to your input value when you enter a value like 2G that cause it warning you

Sorry for my poor english.
>How-To-Repeat:
Answer the questions as follows:

Do you want to change it? [n] y
..
Supply a decimal value for "size" [16776522] 2G
(fdisk asked for Try again due to invalid decimal number)
Supply a decimal value for "size" [16776522] 4194304 
..
Corrent this automatically? [n] y
fdisk: WARNING: adjusting size of partition to 24193827
(not espected value: 4193847 (4193910-63) )

Don't exit fdisk and repeat steps aforesaid, 
the size value of the slice would be as espected.
