# Reproductions/tests for crashes/read errors in TiffDecode.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 pytest test_tiff_crashes.py 2>&1 | grep TiffDecode.c`
|
|
# the output should be empty. There may be Python issues
|
|
# in the valgrind especially if run in a debug Python
|
|
# version.
