testcase.cpp
The attached testcase worked in clang4 and clang5 fine, but it breaks in
clang6:
c.cpp:9:32: error: implicit conversion from '_Complex int' to 'double' is not
permitted in C++
complex_t p = cos (omega) + _I * sin (omega);
^~
c.cpp:6:25: note: expanded from macro '_I'
#define _I ((complex_t)(1i))
~ ^~
Found this on FreeBSD 12 in one port.</pre>
