Hi Martin, Just to be sure I am clear on this when you said it supports both languages: I thought OSC is for C language only since it's listed under "C-Extensions": https://gcc.gnu.org/onlinedocs/gcc/C-Extensions.html#C-Extensions As examples, does OSC support multi inheritance, templates, iterator, copy constructor, member initializer, etc. as well as C++11/14 features such as map, set, etc. which all involve object sizes in some way? Thanks!

Is there any work in progress for C++? I understand checking on C++ object sizes is a lot more difficult but would like to know if such effort exists.... It works in both languages. With the exception of a couple of minor enhancements that I've done some work on in the GCC 7 and 8 cycles that either weren't accepted (bug 77608) or that I'm not done with yet (bug 83859) there is no work that I'm aware of. What kind of C++ extensions do you have in mind? Martin
