+Subject: [PATCH] Fix compilation with GCC 10 by providing explicit cast of
+ _bindingCount
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Compilation with GCC 10 fails with the following error:
+
+service/../osdep/Binder.hpp: In member function ‘void ZeroTier::Binder::refresh(ZeroTier::Phy<PHY_HANDLER_TYPE>&, unsigned int*, unsigned int, std::vector<ZeroTier::InetAddress>, INTERFACE_CHECKER&)’:
+service/../osdep/Binder.hpp:376:30: internal compiler error: unexpected expression ‘(std::__atomic_base<unsigned int>::__int_type)((ZeroTier::Binder*)this)->ZeroTier::Binder::_bindingCount’ of kind implicit_conv_expr
+  376 |       _bindings[_bindingCount].udpSock = udps;
+      |                              ^
+
+Help the compiler by providing an explicit cast to the appropriate type like it
+is already done in l. 338 of the same file.
