Barry Revzin <barry.revzin at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |barry.revzin at gmail dot com --- Comment #1 from Barry Revzin <barry.revzin at gmail dot com> --- Here's a different, C++20-specific test case: constexpr bool f() { int* a = new int; int* b = new int; bool result = (a == b); delete a; delete b; return result; } static_assert(!f()); Also rejected as non-constant comparison.
