Hi cafe,
I ran into a segfault while working on some database code. I eventually
traced it back to a double-finalizing of a statement (read: freeing memory
twice), which ultimately led back to switching my code to use the ContT
monad transformer. I was able to isolate this down to a minimal test
I died in more dependencies. One, ige-mac-integration. To avoid possible
problems I uninstall all ports last night to reinstall full gtk2 with quartz.
For now, i'm solving all of this and I hope to get it working this night.

Hi,
Here's my guess. Take a look at this version, and try running it:
===
{-# LANGUAGE PackageImports #-}
import qualified MonadCatchIO-transformers Control.Monad.CatchIO as C
import Control.Monad.IO.Class
import Control.Monad.Trans.Cont
bracket_' :: C.MonadCatchIO m
= m a -- ^
Hi,
when I install packages from cabal, the package manager installs already
installed files (some of his favorites are process and haskell98)
so these packages are both system and user installed (that can cause later
dependency problems, but the cabal FAQ explains very well how to recover
from
I think you're correct, but I still don't know how to solve it. Any thoughts
on that front? I'm at the point of just attaching a finalizer to the
statement, or sticking in an IORef to ensure it doesn't get
double-finalized.

Hi,
I ran into one problem worth mentioning while recompiling gtk and its
dependencies as universal libraries using macports: the pango port
refused to build with +universal (it fails when trying to merge the
i386 x86_64 libs). The pango-devel port does work with one small
tweak as described at

Hi, all,
bitspeak is a small proof of concept application that allows
writing text using only two commands (yes/no, 1/2, top/down etc.).
It is intended to show how people with disabilities similar to
Stephen Hawking's (i.e., good cognitive hability, but very few
movements) can write text.

Hi Markus,
I am afraid your questions are formulated quite narrowly so that people
you might like to reach might not feel addressed -- so it might be
helpful to ask yourself how your subject might look in the perspective
of an average Haskeller, if a such dies exist at all.
