no.. i know i have plenty of available space. i am just going to unmount
the partition (unfortunately its /home) asap, and run e2fsck on
it. however, i am still very much interested in what caused this, and if
it could be replicated. because this could be a possible root hole in
ext2, although how i would find out more about exploiting this i dont
know. all i know is that a segfault is probably exploitable. Thanks
all for the help though :)
