          Issue ID: 22854
           Summary: static foreach byCodepoint segfault (2.099-rc.1)
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: regression
          Priority: P1

import std.uni;

void main()
{
    static foreach (ch; unicode.Control.byCodepoint) { }
}

This segfaults on DMD 2.099-rc.1.

From looking at the longer DMD debug mode backtrace on master, there seems to

be a stack variable destructor call that reads dead stack memory?
