Adding RustConfig file with VERSION="1.45.2" prevents the problem, but locally builds and with version 1.46.0 successfully...

This looks like it's probably a rustc issue, possibly fixed in the newest release if I understand what you're saying correctly.

ArtHome12 commented 4 years ago

Yes, you are right, now it is already clear that this is a rustcproblem

emk commented 4 years ago

Great! Glad you figured it out.
