	You missread the GPL. Ask a lawyer for help.

The GPL demands (in case you ship binaries and only in this case) no more than 
to put the GPL work under GPL and to make anything, needed to re-create 
the binary, to be made available under a license that allows redistribution.

See e.g. the book about the GPL from the lawyers of Harald Welte.

See page 85 (PDF page 60) see the lower half of the paragraph numbered "23".

	I recommend you not to repeat false claims from uninformed people. 

If you did read the CDDL, you did of course know that the CDDL places "work
limits" at file limits and that the CDDL does not try to impose any 
restriction on sources that are not in a file marked as CDDLd. So the CDDL of 
course does create any restriction on a GPLd work.

On the other side, the GPL does create restrictions on other sources, but it 
just requires other sources (if needed to recreate the shipped binary) to be 
shipped together with the GPLd work. The GPL of course does not impose any 
further restrictions on _other_ sources under a different license.

Given the fact that the official cdrtools source tarball includes everything to 
recreate the binary, everything is legal unless you make unlawful changes to 
the original source.

So calm down, read the GPL and the CDDL by your own - repeat this - until you 
fully understand both licenses.
