Presumably, this means your data source manager is doing something wrong.
The location of the crash suggests it's probably associated with a
resync_to_restart callback, which would be a likely place for bugs to lurk
unnoticed since that function is never invoked except when seeing
corrupted input data.  You might find it useful to read the comments for
jpeg_resync_to_restart(), which is the library's own version of
resync_to_restart.
