John Ralls b4b8431984 Bug 798778 - GnuCashquits abruptly when attempting to edit options… ... for certain reports. Those reports being ones using complex options, apparently because the callbacks weren't protected from Guile's garbage collector. So replace the anyway ugly hack of a void* with a std::any wrapping a class holding a std::unique_ptr with a custom deleter. The constructor calls scm_gc_protect_object on the SCM containing the callback and the custom deleter calls scm_gc_unprotect_object. The copy constructor, required for std::any, makes a new std::unique_ptr and calls scm_gc_protect_object again ensuring that the protect and unprotect calls are symmetrical. Meanwhile std::any hides the Guile dependency from all the classes that don't need to know about it. The only ugliness is that there's no good place to put a common implementation of SCNCallbackWrapper so it's repeated in gnc-optiondb.i and dialog-options.cpp.		3 years ago
