Hi,
talking about good reasons to activate on the list (despite the initial
reaction of going deeper into lurking mode), I just got a patch for
another fairly embarrassing bug (committed to git and will be in 2.8.2):

audioio-wave: RIFF header chunk size too small
When creating RIFF WAVE files, the chunk size of the very
first RIFF block was calculated incorrectly, and was off by
4 bytes.
--cut--
Now the size of the actual data block is correct, so AFAIK this should not
have much practical impact, but in theory some tool could interpret wav
files created by ecasound to have 4 bytes less than they actually do. The
bytes do get written, but the size field of the very first chunk ("RIFF"),
is off by 4.
Arto (cc'ed), sorry, the bug you reported 11 years ago, well, the fix was
not quite correct:
