# CPython uses function pointer casts extensively (PyCFunction signatures
|
||
|
|
# don't match the actual function types). These are "safe" in practice
|
||
|
|
# on all ABIs CPython targets, but UBSan flags them.
|
||
|
|
#
|
||
|
|
# The primary defense is -fno-sanitize=function,vptr in compile flags.
|

|
|
# This file is a backup for any that slip through.
