As I said, I seem to be a magnet (:-)), or maybe a canary in this case,
as this one seems to be brand new.

[Not sure if it's preferable to post this sort of thing to the development
list?]

With the posts yesterday about morphing and PVS etc., I went to play
with pvsanal.csd from the examples.  I was surprised that I was only
hearing two events in each section, despite there being three in
the score!  With some playing around this seemed to be a function
of the 's' statements in the score, so I made a short test file that
shows the same effect (below).

I was doing this in Haiku, so to make sure I took the file over to
Linux -- where it played perfectly!  Then I realized that Haiku is
currently 6.13, but Linux runs the 6.12 distribution.  I do have a
6.13 compiled on Linux, though, so I tried that, and -- sure enough --
I lost the same notes!  My two Linux versions are:

 OK:
 --Csound version 6.12 (double samples) Nov 27 2018
 [commit: 25f21b66c9e22a80089bf0ab5b8db3bf4331876a]

 Misses note:
 --Csound version 6.13 beta (double samples) Mar 13 2019
 [commit: 779ff35e1cd9cc8be23b365adb60d90350b9bd35]


So something has changed pretty recently.  To be more specific
with my tests, I find that the 's' statement kills the immediately
following note, *provided* that there is no intervening newline,
and no comment to the statement.

Here's my stupid test file.  In 6.13, the first note of the second
section is lost.  (Note the protecting comment on the first 's'.)
