Public bug reported:
I was using the autotalent LADSPA plugin with Audacity, and I noticed
that it kept crashing occasionally. I used gdb to track down the cause
of the crashes, and I noticed that there were two problems with
autotalent:
1) A potential division by zero during normalization of audio data may occur,
and
2) Several uninitialized Autotalent struct member variables may be used.
Attached is a patch that addresses these problems. I no longer notice
Audacity crashing with the patched plugin.
