Tokyo has been raining for many days but finally there's some sunny days.

A week ago, release 0.0.5 of the RcppFastAD package went to CRAN, and we noted that it provided a stop-gap measure against a gnarly segfault with g++-16 under heavier optimization / inlining. We are happy to now announce that a new and fixed version 0.0.6 of RcppFastAD is now on CRAN, and has been built for r2u as well as at r-universe.

RcppFastAD wraps the FastAD header-only C++ library by James which provides a C++ implementation of both forward and reverse mode of automatic differentiation. It offers an easy-to-use header library that is both lightweight and performant. With a little of bit of Rcpp glue, it is also easy to use from R in simple C++ applications.

This release takes advantage of some large-language model inference access I now get via Debian. The Deepseek v4 flash-0731 model, driven in a container via the pi.dev harness, took just about no time finding a small workaround for the issue described last week where we could see segfaults under heavier optimization and inlining. The fix was to prohibit inlining the local bind() reimplementation. We have also sent this upstream as a patch. It is nice to have an option of querying something a little more powerful than the local models I experimented with before. We suppress more compiler warnings in local builds via another option, and did some standard maintenance.

The NEWS file for this release follows.

Changes in version 0.0.6 (2026-10-01)

• The expression-template view rebinding is protected against g++ -O3 (which led to wrong Eigen::Map dimensions, an Eigen::Map resize assertion, and a segfault.

• The bind() helpers are marked non-inline and are also protected from operating on a nullptr.

• Both items co-written with DeepSeek V4 Flash, and have been sent upstream in a PR.

• Suppress another compiler warning when local build detected.

• Add r-universe badge to README.md.

Courtesy of my CRANberries, there is also a diffstat report for the most recent release. More information is available at the repository or the package page.
