digitalmars.D.bugs - [Issue 23035] New: -preview=rvaluerefparam causes system function


          Issue ID: 23035
           Summary: -preview=rvaluerefparam causes  system function to be
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: atila.neves gmail.com

Related to https://issues.dlang.org/show_bug.cgi?id=20869, which added this
test to druntime:

 system unittest
    static struct S
        void opPostMove(const ref S old) nothrow  system
            __gshared int i;
            new int(i++); // Force  gc impure  system

    alias T = void function()  system nothrow;
    static assert(is(typeof({ S s; move(s); }) == T));
    static assert(is(typeof({ S s; move(s, s); }) == T));

If druntime tests are compiled with -preview=rvalueparam, the first static
assert fails, since now that function is considered  safe for some reason.
