[PD-dev] block~-overlapped canvases: samplerate wrong for dsp objects

Hi,
i just stumbled over a strange behavior in canvases with overlapped
blocks without resampling (e.g. set with [block~ 1024 2]).
In such canvases e.g. [osc~ 440] delivers a cosine wave with an
actual frequency of 220 Hz, because of the double overlap.
This is because dsp signal vectors carry the wrong sample rate (sp[0]-
>s_sr = 88200 instead of 44100).
[samplerate~] correctly reports 44100 because it uses a different
method of retrieving the sample rate.
I consider that a bug and would file a bug report, but since this
must have been present for a long time and must surely have been
discovered by other people as well it might also be a feature.... any
ideas?
gr~~~
