Haddock Segmentation Fault under Ubuntu 8.04

[fons]

Hi, haddock doesn't work properly under my Ubuntu 8.04 installation.

I'm using the ghc 6.8.2 package distributed with Ubuntu. I tested haddock with the haddock package itslef. I also installed the haddock2 documentation found at http://code.haskell.org/~fons/libraries.html-haddock2.tgz in order to get links properly.

The following listing contains how to reproduce the bug. First I install haddock, then I try to generate the haddock documentation of haddock itself. When I realize that the documentation directory is empty, I run the exact haddock command called by Cabal and I realize that the command segfaults. I also attached an strace listing od the segfoulting command in case it helps.

Hi,

Thanks for the report. I tried to reproduce this with the darcs version, but I couldn't. So it's possible that this problem has gone away since 2.0.0.0.

[waern]

I'm closing this since I've been unable to reproduce it in the latest version, and the reported version is really old.
