Seems to work fine on 2.085.1 or current git HEAD.

I tested this in Arch Linux 64-bit and Windows 10 64-bit and there is no error. This needs a little more investigation. This bug appears to be an issue with a specific distribution or perhaps a bug in one of the OS libraries DMD is liked to. Please describe in more detail on which platform is this symptom appearing.

> Have you tried with -g option? I can reproduce with it. Ok, with `-g` it fails on Arch Linux 64-bit, but not on Windows 10 64-bit.

Ah, yes, this regression only occurs non-windows platform.

I ran a digger bisection to try to identify the PR that caused this regression. It reported https://github.com/dlang/dmd/pull/9364 That isn't very precise, but by educated guess, it appears to be https://github.com/dlang/dmd/pull/9357

It reported https://github.com/dlang/dmd/pull/9364 If you get a merge as a result of doing a bisection of the master branch, performing the bisection against the stable branch will usually find the actual PR (or vice-versa).
