A bunch of fails and then interrupted by segfault a quarter of the way thru. Not a regression from previous pillow, unknown whether cpython regression yet. Log taken with MAKEOPTS="-j1" for clarity.

../Pillow-10.2.0-python3_11/install/usr/lib/python3.11/site-packages/PIL/Image.py:420: RuntimeError: Error setting from dictionary
Created attachment 883142 [details] gdb context and complete backtrace Looks like the crash is actually in media-libs/tiff. Also, it doesn't reproduce when just running the crashing test by itself, or even the entire file. Only crashes when the entire test suite is run.
Not a libtiff regression, or at least not a recent one, downgrading to 4.5.1 does not help.
Perhaps try ASAN or valgrind (if available).
