Yep, there is a bug in 1.11.0.
In Create.c, line 209,
else {
ldsize = dsize;
dsize <<= 9;
}
should be
else {
ldsize = dsize;
ldsize <<= 9;
}
It only affects systems where ioctl(BLKGETSIZE64) doesn't exist or
fails.

size should be a simple integer, no suffix, and it wouldn't let you
create an array using more space than it thinks exists anyway.
I guess it is time for a 1.12 ??
