utils/optional_test.cpp: gcc 13+ complains about -Wmismatched-new-delete issues #239
Description
I've seen this issue with gcc 13 on Ubuntu and gcc 14 on Fedora. It's likely an issue with gcc in general.
Another LLVM bug report claims it's a bug with gcc, but I'm not convinced that is the case. clang doesn't gripe about this, regardless.
