Description Iain Buclaw 2020-06-15 16:27:32 UTC 
As druntime manipulates user stack and doesn't support shadow stack from Intel CET.

This _might_ be a problem on linux/glibc platforms that are configured to make use of this feature, but I haven't looked too hard at it to give a definitive yes/no.

Confirmed, druntime won't work on platforms with Intel CET enabled.
