--- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Quoting: https://gcc.gnu.org/onlinedocs/gcc/Code-Gen-Options.html#index-fexceptions """ -fexceptions Enable exception handling. Generates extra code needed to propagate exceptions. For some targets, this implies GCC generates frame unwind information for all functions, which can produce significant data size overhead, although it does not affect execution. If you do not specify this option, GCC enables it by default for languages like C++ that normally require exception handling, and disables it for languages like C that do not normally require it. However, you may need to enable this option when compiling C code that needs to interoperate properly with exception handlers written in C++. You may also wish to disable this option if you are compiling older C++ programs that don’t use exception handling. """
