Do you use std::vector when working with SIMD? I find the SIMD alignment requirements make it difficult to integrate intrinsics with the rest of my code. Maybe I'm just missing something, but I'm having a hard time with it.

That's a good point. If you use a custom allocator with your vector then you can be sure of the alignment, although the compiler will pretend to be unaware of it. All that stuff I want for string goes for vector, too.
As for std::string I never find myself using boost for any reason so I'm curious what the indispensable boost feature is for strings. The only thing I want from std::string is the ability to resize it without initializing allocated space, the ability to construct a string from an existing data pointer, and the ability to release the data pointer from an existing string (basically the union of a string a unique_ptr).
