I know of 10 plugins that crash in the latest version (1.0.15), in these
source files:

  revdelay-swh.lv2/plugin.c
  allpass-swh.lv2/plugin.c    (3 plugins)
  delay-swh.lv2/plugin.c      (3 plugins)
  comb-swh.lv2/plugin.c       (3 plugins)

It's a simple problem with the buffer allocation code and I've reported
it to Steve.


We could do with a little script that runs through and tests all
installed plugins to make sure they run OK (maybe using
lv2_simple_jack_host). I had problems with 5 out of the first 6 LV2
plugins I tried - 3 wouldn't load and 2 crashed!
