From original report:

Like sed, perl can be used with -i to change files in-place. However, our tool discovered that the saving procedure is not as safe as sed. The system call trace (from 5.22.1):
open("file.txt", O_RDONLY|O_LARGEFILE) = 3
_llseek(3, 0, [0], SEEK_CUR) = 0
unlink("file.txt") = 0
open("file.txt", O_WRONLY|O_CREAT|O_EXCL|O_LARGEFILE, 0600) = 4
read(3, ...)
read(3, ...)
write(4, ...) ...

Can you supply us with: (a) the list of commands you invoked at the command-line to get these results; (b) some idea of the size of the file in question relative to the size of memory?
Thank you very much.
