I have major troubles with darcs now.

I know from another machine, thar darcs needs 1750M to 

run darcs optimize -reoder-patches:

<quote>

11:cb@kl-nb16-005:~/imsbf% darcs +RTS -M1750M -RTS optimize
--reorder-patches

darcs.exe: getMBlocks: VirtualAlloc failed with: 8 

darcs.exe: internal error: getMBlocks: misaligned block returned

   Please report this as a bug to glasgow-haskell-bugs@haskell.org,

   or http://www.sourceforge.net/projects/ghc/

Version: (Windows XP)

darcs compiled on Jun 16 2006, at 13:00:32

# configured Fri Jun 16 12:59:52 USMST 2006

./configure --disable-mmap

On the remote repro I get a "darcs: failed to read patch in
get_extra"-Message.

I found an email, that darcs optimize -reorder-patches could help.

The latest snapshot of darcs tells me:

<quote>

612:cb@kl-nb16-005:~/imsbf% darcs +RTS -M1750M -RTS optimize
--reorder-patches

darcs.exe: bug in darcs!

Failure commuting patches in commute_by called by gpit!

Please report this to bugs@darcs.net,

If possible include the output of 'darcs --exact-version'.

The output of darcs -exact-version is attached.

And now darcs-1.0.8 check fails: 

darcs failed:  Error applying hunk to file ...

The same message from dacs-1.0.8 repair.

Hmm... I'm just going on the error message here and suggesting that you report
this to the GHC folks.

We do know about the performance issues and are working on it.

Meanwhile I found a solution for me. The command

darcs +RTS -M1500M -c -RTS optimize --reorder-patches

succedes. It used up to 1G memory.

GHC Bug Entry: http://hackage.haskell.org/trac/ghc/ticket/1209

I'm not sure about ghc's version, since I used a precompiled darcs.
guess it was 6.4.2.

Marked as fixed on the GHC tracker.
