[src/trunk]: src/tests/lib/libexecinfo Prevent inlining of the main testcase ...
details: https://anonhg.NetBSD.org/src/rev/732abf06ea36
branches: trunk
changeset: 789357:732abf06ea36

description:
Prevent inlining of the main testcase body function.
Do not mark the inner functions static, as they might get cloned then
(ending up being called "myfunc3.clone.3" instead of "myfunc").
