           Summary: Various mixins cause "CompileExp::semantic" message,
                    some crash DMD
           Product: D
           Version: 1.012
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: diagnostic, ice-on-invalid-code
          Severity: major
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com

             nThis:


Some invalid mixins causing compiler crashes, in addition to the message
"CompileExp::semantic('mixin(2)')\n2":

--
void main() {
        cast(void)mixin(2);
}
--
void main() {
        "" ~ mixin(2).stringof;
}
--
char[] s = mixin(2).stringof;
--
auto i = mixin(2);
--

These result in only the message (and the expected errors), no crash:

--
void main() {
        "" ~ mixin(2);
}
--
char[] s = mixin(2);
--
int i = mixin(2);
--

This one also results in the message and, strangely enough, compiles
successfully (the statement is completely ignored):

void main() {
        cast(void)mixin("2");
}

Setting Bug 1146 to depend on this, although it's probably just another
instance of the same bug, and could be set as being a duplicate.
