Thank you for testing my code and for help with dub.
I have rebuilt SDL2 from source. Unwrapped macroses and found 
that the error in the next code:

     __m128 c128;
     Uint32 __attribute__((aligned(16))) cccc[4];
     cccc[0] = color; // THE ERROR IS HERE
     cccc[1] = color;
     cccc[2] = color;
     cccc[3] = color;
     c128 = *(__m128 *)cccc;

Valgrind shows it as:

==17988== Process terminating with default action of signal 11 
(SIGSEGV)

But it really doesn't help..
