crashing plugins

[oget]

I originally filed this bug to zynjacku:
https://gna.org/bugs/?13688

The problem was, loading some of the lv2-swh plugins via zynjacku resulted in segmentation faults, while the plugins work fine with lv2_jack_host (from slv2) or ardour.

I have been asked to file this bug here. I went through all the plugins one-by-one, and meanwhile I noticed that some of them crash with even lv2_jack_host (which I misreported before). What is not listed in the below list works fine.

Note that, this test is made against the latest trunk snapshot + the patch I submitted in
http://github.com/swh/lv2/issues#issue/1
(otherwise more plugins will fail due to missing symbols)
