Hi folks,

Both types use atomic reference counters, both types have C++ headers (mir-algorithm package). They are aimed to develop a user-friendly @nogc code and integrate tons of C++ code into D code using a step-by-step approach.

Sounds great, but wrong-code issues adds some problems.

2. https://issues.dlang.org/show_bug.cgi?id=19793

For the first issues please use a reduced example by ag0aep6g. The original example is more complex and likely combines both of them.

Both issues can affect on generic Phobos parts and user-defined libraries as well. I would say any serious infrastructure with manual memory management is likely affected.

Best,
Ilya
