           Summary: DoS code on Windows Platform
           Product: D
           Version: 1.009
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: davidl at 126.com


static char[] hello()
{
        char[] result="";
hello:
        result ~= `abc`;
        goto hello;
        return result;
}
void main()
{
        pragma(msg,hello());
}

what i want to say is DMD should limit the memory use of CTFE.
if CTFE keep use memory at a certain level and release some, reallocate some,
then the situation would be a disaster of compiling.

probably we should have a compile option to limit the compiler's use of
memory. if exceeds then break the compilation

buggy code could easily drop into an endless loop in CTFE
