Comment (by tenzap):

 Replying to [ticket:64055 tenzap]:
 > Originally, when building KeePassXC on macOS 10.11 with a compiler that
 supports the -fsized-deallocation (like clang++-mp-9.0, or a recent
 AppleClang, probably >= 8) there is this error:
 >
 > {{{
 > error: call to unavailable function 'operator delete': introduced in
 macOS 10.12
 > }}}
 >
 > Test case file to compile with `-fsized-deallocation` flag:
 > {{{
 > #include <new>
 > int main() {
 >   void * ptr = nullptr;
 >   std::size_t size = 1;
 >   ::operator delete(ptr, size);
 > }
 >
 > }}}
 >
 >
 > Maybe this is part of the things that could be addressed by
 legacysupport?
 >
 > There may be other related functions missing since delete is
 'overloaded'
 > https://en.cppreference.com/w/cpp/memory/new/operator_delete
 > https://en.cppreference.com/w/cpp/header/new
 >
 > For now this is worked around in KeePassXC with a patch that disables
 use of -fsized-deallocation on macos < 10.12.
