это видно даже по тому багрепорту, ссылку на который ты указал

А в gcc - эти баги висят годами и они нах никому не упали фиксить их.

Hi folks!

Sorry for the confusion here. This might be somewhat misleadingly marked "fixed pending release." The problem is that this issue is caused by the DLL interface exposed by msvcp140.dll. It passes struct xtime instances back and forth, which are effectively UNIX timestamps against the system clock. Changing that interface is unfortunately an ABI breaking change. VS2017 and 2019 have been ABI compatible releases with VS2015, so we haven't been able to fix this paritcular bug there. (I think this_thread::sleep_for might be fixable with some hacks and a new msvcp140_3.dll, but condition_variable::sleep_for, probably not)

The reason this got marked as fixed pending release is that we already have changes staged in our ABI breaking branch that completely rewrite all the concurrency support in the standard library to fix this and *many* other bugs. So we have a branch with this fixed, and as soon as we can ship an ABI break it will be fixed, but unfortunately people really like the ABI compat guarantees.

As a result we don't really know exactly which release will contain the fix. We (the standard library team) have done the work; we are only waiting to ship it till the number of customers angry about ABI breaking bugs remaining unfixed exceeds the number of customers happy that lack of ABI break means they don't need to recompile the world.

Have a great day!
