[ladcca] Segfault with LASH 0.4.0

[Josh Green]

Hello, I just now got around to applying the FluidSynth LADCCA patch
present in 0.4.0 to FluidSynth CVS.  In the process of testing I
discovered a bug in ladccad.  If FluidSynth is started, then stopped,
then started again (both times connecting to ladccad), on the second
connect ladccad will crash.  Of note is that this does not occur when
--enable-debug is supplied to configure.  Here is output from gdb:

Note that I left out the complete display of the "ss" variable in frame
#2, since it had some invalid chars that my email program didn't like.

FluidSynth displays this, on the second invocation:
cca_comm_recv_run: recieved unknown event of type 0

Ciao!
