Your file system is corrupted, and there are two bugs. (1) e2fsck
wasn't detecting this form of file system corruption (a zero-length
extent entry), and (2) the kernel was not noticing until an assertion
check using BUG_ON, instead of flagging this as a file systme error.
The fixes for both of these problems, in the kernel and in e2fsprogs,
are here:
