Another thing to note is that (IIRC) the AIFF specification makes a
point that only one SSND chunk is allowed. Even if it weren't for
the total file size in the FORM chunk at the start of the file, you
still cannot have a valid AIFF with anything except exactly one SSND
chunk.
You are correct that a bug report is prudent. Crashing should never
be a result of API calls (unless you pass a bad pointer or something).

Thanks - that would explain the write error, but it shouldn't crash
ExtAudioFile, right?
Maybe it's time to file a bug...

Well, my understanding of the AIFF/AIFC specs was that if you have
more than 4GB of data this would be broken down into separate chunks.
Does ExtAudioFile not do this for you??
Also, I have the same problem with WAVE files - do they also use
32bit
offsets?
Both AIFF and WAVE keep a 32-bit "total file size" marker at the
start of
the file. This prevents either format from going past 4GB without
extensions.
