diff 2.7 eating up all swap

[Uwe Bonnes]

Hallo,

some days ago I had the opportunity to have a spare disk available. As I
wanted to  reformat some partition from ext2 to reiserfs ( under linux/suse
7.0) I plugged the disk into my PC, made some new partition and copied the
partition to reformat to the new partition (cp -a ...). To check, I wanted to
diff those two partitions ( diff -uwr ...). 

At some point in that process, diff (version 2.7) began to eat all available
memory (256 MByte Ram, 512 MByte Swap). I could only abort the diff
process. In that situation, I couldn't get any usefull information that
could help to point to the error. I tried several times again, even with
arguments swapped, and I could always triggered that behaviour. 

The spare disk has found another use in the meantime, so I can't reproduce now.

Bye
