It is caused by Regression in core.atomic. Since we are making a pull request, please wait a little longer for the compiler to fix it.

Robert-M-Muench commented 4 years ago

Ok. Going back to 088 and see if this works.

Robert-M-Muench commented 4 years ago

Doesn't help, need to switch to go back to RX 0.10.1 release.

lempiji commented 4 years ago

It was fixed in 2.090.0-beta. Please let me know if you have any other problems.:smiley:

Robert-M-Muench commented 4 years ago

IMO it was fixed in 2.089.1 see: https://dlang.org/changelog/2.089.1.html
