Hello, we are testing AAC and FLAC support with Liquidsoap, and finds that
it seg-faults on a wide variety of files (files from iTunes or randomly
downloaded samples from the internet):
Output is posted at the end of this email. We have a ticket open here
http://dev.sourcefabric.org/browse/CC-4468 where you can download the
samples (try "thunder_128k.m4a").
The issue happens on both Debian Squeeze and Ubuntu 12.04 (natively
compiled on both machines).
Here is the command used and the output:
martin@Thinkpad-T410:~/tmp/liq$ liquidsoap 'output.ao
(single("thunder_128k.m4a"))'
