package: csound
version: 1:6.12.2~dfsg-1
severity: important
justification: Regression over stretch with insidious and
hard-to-diagnose consequences



I noticed that  my orchestras were failing on several sound files after
upgrading to buster, and tracked it down to some cases of  filenames
being input in the score file.

Consider the following orchestra and score:

Orchestra:

0dbfs=1
sr=44100
nchnls=4
instr 1, 10
Sfile strget p4
amic = 0
a1, a2 diskin Sfile, 0.997, -2.3

vincr amic, a1
outq amic, amic, amic, amic
endin


Score:

----------------------------------------

Somehow in the buster code path, The space between Album and Mix has
been removed and the filename has become corrupted.
Note that the buster code path works fine if  you hard code the sound
file name in the instrument.
It's something to do with the score file that is problematic.

I apologize that the score is a bit complex; it's obviously extracted
From some more complex code.  My typical orchestra is quite complex and
I wanted to get things down to an debuggable minimal example, but I also
wanted to  use the production score file.
I'm also attaching the score as a mime attachment because it is a rather
long line.
