Access of Uninitialized Pointer in jpc_enc_cp_destroy

I build jasper with clang-11 (also an error in clang-9).

Build :

$ cd jasper/build 
$ export CC='clang-11 -fsanitize=address'                                                                                              
$ export CFLAGS='-g'
$ cmake ..
$ make -j 8

poc : poc.zip

reproduce :

➜  appl git:(master) ✗ ./jasper --input ./poc --output ./test.jp2

I also try to use --debug-level. This tries to free error memory
