That's indeed an intersting question. Maybe files of these dimensions simply exceed the specifications (or expectations) of a WAV file.

But when I try to play file with:
   rhytmbox
   mplayer
   totem
   sox
all of them see file duration 0:46:26. (sox says: Duration: 00:46:26.50)
I have seen the same result with another extracted-DTS-to-6ch-wav
conversion, in that case sound was torn in some other wrong duration.
The same result if writing to pipe.

I don't know the mediainfo tool (it does not seem to be available from the Debian archive), but I guess that the aforementioned packages all pretty much share their WAV-decoding code. What does the file(1) utility say (what does ffmpeg say) and what happens if you put the WAV file back into a container, say MKV or OGG?

In addition to this one, there is error with output-error handling:
in case of running out of disk space (that is very possible with
so giant WAVs) no error reported, no error status returned, and
decoding process continues to nowhere.

Alright, that's a completely different issue (and certainly worth its own bug report) and I'll try to have a look at it sooner or later.
