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. https://software.intel.com/content/www/us/en/develop/articles/intel-sdm.html

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