The issue #23545 enabled extra warnings on GCC. Clang on FreeBSD now complains about unreachable (dead) code: http://buildbot.python.org/all/builders/AMD64%20FreeBSD%20CURRENT%20Non-Debug%203.x/builds/281/steps/compile/logs/warnings%20%2814%29 Python/ast.c:3133:5: warning: code will never be executed [-Wunreachable-code] Modules/posixmodule.c:10256:5: warning: code will never be executed [-Wunreachable-code] Modules/zipimport.c:1004:22: warning: code will never be executed [-Wunreachable-code] Modules/faulthandler.c:988:5: warning: code will never be executed [-Wunreachable-code] See also my change ea00c88f7f42 which fixed a similar issue in Parser/grammar.c. See also the issue #14656.
