#103 Referring to any non-static member or base class of an object in the handler for a function-try-block of a
constructor or destructor for that object results in undefined behavior: eel.is/c++draft/excep…
#104 If the token defined is generated as a result of this replacement process or use of
the defined unary operator does not match one of the two specified forms prior to macro replacement, the
behavior is undefined: eel.is/c++draft/cpp.c…
#105 If there are sequences of preprocessing tokens within the list of arguments to a function-like macro
that would otherwise act as preprocessing directives, the behavior is undefined: eel.is/c++draft/cpp.r…
#109 When using the pptoken variant of the #line directive, If the directive resulting after all replacements does not match one of the two previous forms, the behavior is undefined.: eel.is/c++draft/cpp.l…
#110 If any of the pre-defined macro names in [cpp.predefined], or the identifier defined, is the subject of a #define or a #undef preprocessing directive, the behavior is undefined: eel.is/c++draft/cpp.p…
#115 Calling a function through an expression whose function type is different from the function type of the called function’s definition results in undefined behavior: godbolt.org/z/snjzbh6oc
#116 If the substitution of template arguments into a requirement would always result in a substitution failure, the program is ill-formed; no diagnostic required: godbolt.org/z/eez98bfT5
#117 If, during parsing, lookup finds that a name in a template argument is bound to (part of) the declaration being parsed, the program is ill-formed. No diagnostic is required: godbolt.org/z/z354fnYGa
#118 If no arguments to a constexpr function allow it to be used in a core constant expression context,
the program is ill-formed, no diagnostic required: godbolt.org/z/MdnsWe69E
#119 If no specialization of
the template would satisfy the requirements for a constexpr function when considered as a non-template
function, the template is ill-formed, no diagnostic required: godbolt.org/z/8rMd18rPj
#120 If constinit is applied to any decl of a var, it shall be applied to the initializing decl. No diagnostic is required if no constinit declaration is reachable at the point of the initializing declaration: godbolt.org/z/bWMaTh8Ed
