Package: e2fsprogs
In lib/ext2fs/icount.c(get_icount_el) there is some code which looks
like this:
/* Interpolate for efficiency */
lowval = icount->list[low].ino;
highval = icount->list[high].ino;
if (ino < lowval)
range = 0;
else if (ino > highval)
range = 1;
else
range = ((float) (ino - lowval)) /
(highval - lowval);
mid = low + ((int) (range * (high-low)));
I had a file system where range ended up being 1.0f, low being 0 and
high being a large number.
Due to how floating point works, this meant mid ended up being > high
and the while loop never terminated.
Clamping the mid value to be <= high and >= low fixed this problem.
