Yes, among other issues, see http://gcc.gnu.org/wiki/Cxx11AbiCompatibility and http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53657 > Or can I expect to see issues combining GCC 4.7.0/4.7.1 code with 4.7.2 > and later? Yes, if the 4.7.[01] compiled code uses std::list in C++11 mode. > If so is there a patch I can apply to my GCC 4.7.1 to proactively fix > this up, since 4.7.2 is still a few months away from release?
