I didn't manage to get to the bottom of which
piece of software
was causing the problem.
Sorry, it is both jack_rec and jack_capture.
Both use libsndfile, and neither should behave differently
when running on a 32 bit OS.
*From the POV of libsndfile, it has had Large File
Support (which
*makes file offsets 64 bit signed values) on 32 bit systems for over
a decade.
J.C: Could it be that your libsndfile is that old?
However, it is possible for other software using
libsndfile incorrectly
(ie using a 32 bit integer to store file offsets) to cause this sort
of a problem, but then I would expect it to go wrong on 64 bit systems
because `int` is 32 bits there too. However on 32 bit Linux systems,
`long` whereas it us 64 bits on 64 bit Linux systems.
Yes, but neither jack_rec or jack_capture uses long for this (jack_capture
uses int64_t), and jack_rec doesn't even use a counter, it just writes
and writes
until it stops. jack_capture has a counter, but that counter is only
used when writing
wav files, and only used to keep track of when to start writing on a
new file when reaching
the 4GB barrier.
