# Reproductions/tests for OOB read errors in FliDecode.c

# When run in python, all of these images should fail for
 | 
						|
# one reason or another, either as a buffer overrun,
 | 
						|
# unrecognized datastream, or truncated image file.
 | 
						|
# There shouldn't be any segfaults.
 | 
						|
#
 | 
						|
# if run like
 | 
						|
# `valgrind --tool=memcheck python check_jp2_overflow.py  2>&1 | grep Decode.c`
 | 
						|
# the output should be empty. There may be python issues
 | 
						|
# in the valgrind especially if run in a debug python
 | 
						|
# version.
