Hi Guillem, I was about to file a bug against clang-3.3 but what I discovered looked like more a bug in dpkg. It's probably related to the recent optimizations that concerns management of file lists.
In today's dist-upgrade: Unpacking llvm-3.3 (1:3.3-13) over (1:3.3-12) ... Preparing to unpack .../clang-3.3_1%3a3.3-13_amd64.deb ...

(This is the french string for a file conflict detected by dpkg) Strangely, the next "apt-get -f install" fixed it even though llvm-3.3 had already been unpacked and thus nothing was supposed to change.

It also has the same Breaks (not Conflicts). AFAIK the Replaces alone should have been more than enough, here it looks like that dpkg has kept ./usr/lib/llvm-3.3/bin/c-index-test associated to llvm-3.3 even though that package has been upgraded. The next dpkg run fixed this (possibly because it reloaded the file list from the disk instead). I have created a minimal test case for this, it's attached and I can reproduce the problem with it: # test-one-run-ordered sudo env dpkg --admindir=/home/rhertzog/deb/core/pkg-tests/t-file-replaces-versioned/../dpkgdb --force-unsafe-io --no-debsig -i pkg-file-original-0.deb pkg-file-takeover-0.deb Selecting previously unselected package pkg-file-original.
