Hi LuckyBoy, It looks like your compiler is crashing, which is definitely a bug in the compiler, not in Cap'n Proto. Is this really an unmodified build of Clang 3.5? Are you targeting an unusual architecture, or is there anything else unusual about your compiler configuration? I tested 0.6.0 using Clang 3.5 on Linux before release and it worked for me.
