Comment 10 for bug 331342

I'm impacted by this bug as well, as the 32-bit binaries shipped with the Bzr installer run out of memory when migrating my huge SVN repos with 50k files, ~24k revisions, and ~25GB of data.

I tried building bzr from source on 64-bit Python 2.6, but the missing zlib header files tripped me up. In case anyone's interested this is the error I got after doing a 'python setup.py build':

bzrlib/_chk_map_pyx.c(32) : fatal error C1083: Cannot open include file: 'zlib.h': No such file or directory

  Cannot build extension "bzrlib._chk_map_pyx".
  Use "build_ext --allow-python-fallback" to use slower python implementations instead.

At any rate, I don't think it's realistic to count the build from source option as a viable workaround, at least not as of now.

Incidentally, I had almost the exact same problem trying to migrate this repos to Mercurial. It really sucks as it's preventing me from migrating our team away from SVN
