I have managed to reproduce this a few times in various tests. It seems that
issue1248.sh is just the one that fails "most often", with a number of other
tests failing from time to time. I have seen issue1248.sh pass with same binary
that usually fails, too. All this with stock Debian GHC 6.8.2 (stable). I have
never seen the problem happen with GHC 6.10.3. Moreover, the mentioned patch
does not seem to change anything about this behaviour for me.
The code that is failing seems to reside in Darcs.Lock, likely the atomic write
file operations: writeAtomicFilePS and its helpers. I haven't had more time to
isolate the problem so far. I'll try to resolve this in time for beta 2 though.
