I was curious so I compiled pd-0.52-1 on linux, with DEFDACBLKSIZE set to 16.

I set Jack up with buffer size 16, and run pd with jack backend.

Most of the patches in the help browser works, but at least these objects fail to load:

sigcatch : unexpected vector size
throw~ : vector size mismatch
receive~ : vector size mismatch
sigsend : unexpected vector size

In the options for ALSA, the current block size is displayed correctly as 16 but you cannot select it again once you change it.

i prepared a patch that did that in 2004 or so.
