Checked into GIT 0001-cppcheck-in-trackcanvas.C.patch -- always a good idea to initialize variables

Andrea, I have attached small test file which crashes every time for me.  This is what I get with the attached test:

audio0 pad 16 0 (16)
FFMPEG::open_decoder: some stream times estimated: /root/media1/elephants-dream.webm
FFMPEG::open_decoder: some stream times estimated: /root/media1/elephants-dream.webm
cin: malloc.c:4036: _int_malloc: Assertion `(unsigned long) (size) >= (unsigned long) (nb)' failed.
Aborted (core dumped)

Andrew, keep checking for potential other improvements out there because you never know what you might find.

In the build system of CGG not all the actual dependencies on the C++ header
files are defined. It is very likely that a simple `make all' after change
in some .h header file will recompile some .C files and not recompile some
other .C files which depend on the changed header.

... 

To test if it could be the case is easy: a complete fresh build with
preceding clean-up of all the .o, .a, and .so files.

Thanks for the reminder because it makes a big difference.  Because I have gotten bit by this so many times, I just routinely do "make clean" and then run "bld.sh" that way I know I am testing what I think I am AND I get a coffee break.
