That's good :)

It appears to happen for all inputs.

address@hidden:/usr/src/sources/d/diffutils-2.8.4$ touch a b
address@hidden:/usr/src/sources/d/diffutils-2.8.4$ src/diff a b
src/diff: memory exhausted

This was my configure command:

  $ ./configure --disable-nls --prefix=/usr

## --------- ##
## Platform. ##
## --------- ##

uname -m = i686
uname -r = 2.5.62-mm1
uname -s = Linux
uname -v = #2 Wed Feb 19 22:35:01 EST 2003

gcc version 2.95.3 20010315 (release)

I used these CFLAGS, which normally work fine on this machine:

CFLAGS = -O2 -fomit-frame-pointer -pipe -malign-double 
-mpreferred-stack-boundary=2 -march=i686 -s

Hmm.

I recompiled with the usual CFLAGS= -O2 -g and there is no problem.
I recompiled with the original CFLAGS, and now that is working too.

Sorry, I don't know what the problem was, but there is not one now.

You can ignore the rest of this.  It's very strange, but it's not
a diff problem.  cksum's on the two versions of diff are the same,
but they behave differently.  Note the subtle - at the end of the 
directory path of the one that has a problem.  (that was just where i 
backed up the original compile directory - it has nothing to do
with the different behaviour).

You guys rock.  Thanks for making me look at it again.

Final Hmm.  md5sum is different for the working and non-working
diff commands.
