I would like to upload the contents of portaudio19 19.6.0-1.1
to buster.
[ Reason ]
The current library makes applications crash. Please see
Debian #944509 for the bugreport, but this is also seen
e.g. when testing a polyphone backport which I’ve just
built. Without the crash fix backporting polyphone makes
no sense, and since it is a rather important fix entering
via stable-updates seems sensible (instead of via bpo).
[ Impact ]
Applications using portaudio randomly crash.
[ Tests ]
No automated tests but without it applied, polyphone
crashes after a bit, maybe a minute or two, of using.
[ Risks ]
The patch is rather small and “obvious enough”, so I
consider this zero risk. It has been tested in unstable
and testing for 7 months now.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in (old)stable
[x] the issue is verified as fixed in unstable
[ Changes ]
Apply a patch from the upstream mailing list to fix the crash.
[ Other info ]
The resulting package is, except for the changelog difference
and being recompiled in buster, identical to the one in
bullseye/sid.
