# 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.
