I've set up my Mixxx to load songs from my rather extensive FLAC collection (a one line diff...), and initially a file played fine (Aphex Twin/Acrid Avid Jam Shred), then when playing the exact clone in MP3 synchronised, they were fine... And indeed juggling the fader produced no noticeable difference between the two. However when loading a deck with the other deck playing, I got a libsndfile seek error. This was using JACK as the sound API and the added song was I Heart Hiroshima/Candy Cut.

Subsequently this couldn't be reproduced, but for a bit, adding *any* FLAC caused a crash. Now it works just fine.
I fixed some dangerous code in the libsndfile backend we have, which might help mitigate these crashes. I have the feeling any further crashes you see are not related to the FLAC code, and instead probably due to memory corruption elsewhere.
If you can reproduce a crash like this, run Mixxx under gdb and generate/post a backtrace using the instructions here:
