[Dlang-internal] Issue 17057 merged into master but not in release

[Mike Bierlee via Dlang-internal]

According to github, issue 17057 was merged into master last 
January but doesn't seem to be in any of the following releases. 
I cannot find it in any of the changelogs. When running the test 
on DMD32 on Windows, the bug is still there.
What happened to the merge?
