# 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.
