ASAN problems

C++11 as minimum supported standard

Yes trickier issue. "Eventually" we will make the same subsitution but we probably need to have a 'deprecated' period first where we warn. This is still a user-facing API.

C++11 as minimum supported standard

We're not there yet, but we are moving from wheels that are almost quadratic with their five sides to those with six. Almost a smooth ride now. Kidding aside, many/most...

With Rcpp 1.1.0 at CRAN this can now be closed.

Rcpp sugar indexHash (unique, sort_unique, etc.) distinguish signed and unsigned zeros

Thanks for the note. We will ponder this, Making a change may risk upsetting existing code, but documenting your workaround of adding an explicit zero seems like a good idea.

Rcpp sugar indexHash (unique, sort_unique, etc.) distinguish signed and unsigned zeros

We could try that.

Rcpp sugar indexHash (unique, sort_unique, etc.) distinguish signed and unsigned zeros

I am no compiler expert but looking at your diff I would suspect the 'empty' addition might get optimised away? _Edit:_ No it doesn't. See below.

Yup. ```c++ #include #include double fixup(double d) { return d + 0.0; } double fixup2(double d) { return (d == 0.0 ? 0.0 : d); } int main(int argc, char...

Smarter palette choice / recycling with many groups
