https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290687 Bug ID: 290687 Summary: LIBCPP hardening asserts are enabled with -DNDEBUG which degrades performance Product: Base System Version: 14.3-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: yuri@freebsd.org ---BEGIN test program--- //#define _LIBCPP_HARDENING_MODE _LIBCPP_HARDENING_MODE_NONE #include <vector> #include <iostream> int main() { std::vector<int> v = {1, 2, 3, 4, 5}; std::cout << "last-ptr=" << &v[5] << std::endl; return 0; } ---END test program--- The above program fails with Illegal instruction due to LIBCPP asserts being enabled. Normally all asserts should be disabled with -DNDEBUG but these LIBCPP asserts remain. The hardening mode can be changed by uncommenting the first line in the program. _LIBCPP_HARDENING_MODE should probably default to _LIBCPP_HARDENING_MODE_NONE with -DNDEBUG. -- You are receiving this mail because: You are the assignee for the bug.help
