Hmm. I recompiled 'zlib' with some extra tracing and now the problem doesn't happen. Even without the tracing it is fine. Must have been something wrong with the compiled library. Scary. But, everything is working fine now.
I figured out what the problem is. I've been working in a shared directory with both an amd64 and an x86 machines using the files. I've been going back and forth. I've been blowing away the 'dist' directory and rebuilding when moving from one platform to the other. However, what I missed is that the hsc2hs target files are placed alongside the source, not in the dist directory. I had been building zlib on x86 using the hs generated on an amd64 machine. The offsets in the structures were wrong. How difficult would it be to have Cabal store the target files in the 'dist' directory with everything else? This also makes revision control a little more challenging, because I have to hand-pick a few select .hs files to ignore, since the rest of my code is sitting right next to them. Thanks, David Brown
