This is the tracker for GCC 5.0. Do NOT report bugs here. - create a NEW bug assigned to the maintainer of the package in question (ie. NOT gcc-porting@gentoo.org) - Don't use this bug for issues in GCC 5.0 itself. File a new bug and assign it to the toolchain team. - Please keep this tracker free from comments. Discussion should take place on the relevant bugs.
GCC 5.1 released: https://gcc.gnu.org/gcc-5/ Shouldn't we change the name of the tracker?
One thing to look out for. If you're getting packages failing with undefined references to std::__cxx11 or [abi:cxx11], eg: cmGlobalGenerator.cxx:(.text+0x12781): undefined reference to `Json::Value::Value(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)' it's not a bug. It just means you need to rebuild the package that provided that symbol first. See https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html for more info.
