Isolating this bit:

• The point is, if they switch off RTTI, will exception handling still work properly in GCC? — πάντα ῥεῖ 1 hour ago

The answer is yes:

Disable generation of information about every class with virtual functions for use by the C++ runtime type identification features (dynamic_cast and typeid). If you don't use those parts of the language, you can save some space by using this flag. Note that exception handling uses the same information, but it will generate it as needed. The dynamic_cast operator can still be used for casts that do not require runtime type information, i.e. casts to void * or to unambiguous base classes.
