Was it reverted? It is listed as "Bugzilla 19455: GC wastes too much memory". What's not found in the changelog is an optimization sweeping large allocations that is inspired by your report https://forum.dlang.org/thread/zrouxhbkssrncyinh...@forum.dlang.org: https://github.com/dlang/druntime/pull/2430

Here are some related bug reports: https://issues.dlang.org/show_bug.cgi?id=3463 https://issues.dlang.org/show_bug.cgi?id=4358 https://issues.dlang.org/show_bug.cgi?id=9094 https://issues.dlang.org/show_bug.cgi?id=13801 https://issues.dlang.org/show_bug.cgi?id=18900 Precise heap and data segment scanning isn't the complete solution, though, The stack and registers might still contain false pointers.
