Hi: Working with today's build. Post cleanup of gcm.cache, I create a system header unit for "print" header file. Now, when I use "import <print>;" in the code, following error is seen fatal error: failed to load pendings for ‘std::__format::__do_vformat_to’ compilation terminated. However, no such error is seen when i use "#include <print>". Any pointers as to what I could be missing or work around to get this to work ? warm regards Saifi.
