Hello,

I've downloaded the ghc darcs repository, and made the following patch:

    hunk ./README 55
    -  This grabs the "boot" packages by default.  To get the full set
of
    -  packages, instead say
    -
    -     $ ./darcs-all --extra get
    -
    -  This also downloads the libraries that are normally bundled in
the
    -  "extralibs" package (see above).
    -

I recorded it with darcs record, and then tried to edit it with darcs
amend --edit.

After editing, I got:

^C^C^C^C^C^C^C^C^C^C^C^@Morto

Morto means killed in pt_BR.

The first time it consumed all my 3GiB of RAM and after I pressed C-M-F1
to get to tty1 it took a while before I could killall -9 darcs.

In the second try I tried pressing C-c to stop it, but I couldn't, and I
had to go to tty1 again to kill it.

Greetings.

Marco: can you reproduce this?

If so, is the --edit flag relevant at all? (I'm guessing not, but if you could
check, that'd be great)

Furthermore, what happens if you unrecord and then record, instead of amending?

No, I can't reproduce it in the darcs version of darcs.

Greetings.
