           Summary: invalid free during AssertError destructor
           Product: GDC
           Version: 0.18
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos

     70     {
     71         assert(false, "test 6 " ~ test5func());
     72         writefln("test 6 failed -- it didn't throw when it should
have");
     73     }
     74     catch (AssertError e)
     75     {
     76         if (e.msg == "test 6 message")
     77             writefln("test 6 passed ");
     78         else
     79             writefln("test 6 failed -- threw the wrong message");
     80     }

I can't reproduce this with dmd 0.160 so I'm assigning this to gdc for now.  It
could well be something in the front end or phobos since I haven't dug into it
much.
