Even though _Static_assert() is pretty robust for C code, it cannot work correctly with C++ code. This is due to the fact that C++ template parameters may contain commas that are not enclosed in parentheses. For example: static_assert(foo<int, int>::bar == baz, "..."); This causes _Static_assert to be called with an excessive number of parameters. If you want to use static_assert in C++, just use a C++11 compiler. Reported on: current@, ports@
