Csound LADSPA Plugin

This is the Csound plugin for LADSPA.

Building

CsLasdpa requires Csound to be installed in the system, as well as CMake. With that in place, to build the plugin you do

$ mkdir build
$ cd build
$ cmake ..
$ make

csladspa's Issues

csladspa cannot open corrsponding csd-files

After cloning csladspa repos and building csladspa, testing fails with the included example CSOUNDladspa csd files, giving the message:
attempting to load plugin index: 0
PLUGIN NOT LOADED: probably missing csLADSPA section
no more csLADSPA plugins

$ echo $LADSPA_PATH
/usr/lib/ladspa

$ ls -1 /usr/lib/ladspa/

csladspa64.so

$ analyseplugin csladspa64

$ uname -r
5.9.0-4-amd64

/usr/lib/ladspa/csladspa.so calls free() on something it shouldn't

If I have the cslapspa package installed on 18.04 (this has been reported on 17.10 as well) it causes many apps to crash (Hydrogen, LMMS, Non-Mixer, Ardour, etc) with this message:

free(): invalid pointer
Aborted (core dumped)

Looking at the corefile stacktrace I see this:

#0  0x00007f608bd5ae97 in __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51

#14 0x000000000046d2cb in main ()

So it looks like ladspa_descriptor() is to blame.
