Probably in some other places as well:

LZ4_initStream() can return NULL, but the code immediately derefs
the pointer.  The assert() check seems to be misplaced, unless I'm
missing something.

I suppose those need to be decoupled.  First LZ4_initStream() call and
NULL check, then stream->internal_donotuse.
