Was this supposed to say `const A * const`? (Also in test4) As is, clang
warns

catch_const_pointer_nullptr.cpp:56:20: warning: duplicate 'const'
declaration specifier [-Wduplicate-decl-specifier]
    catch (const A const*)
                   ^~~~~
catch_const_pointer_nullptr.cpp:75:20: warning: duplicate 'const'
declaration specifier [-Wduplicate-decl-specifier]
    catch (const A const*)
                   ^~~~~
