--------------------+---------------------------
 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 added to legacysupport?

 For now this is worked around in KeePassXC with a patch that disables use
 of -fsized-deallocation on macos < 10.12.
