           Summary: Segfault using tuple in asm code, when size not
                    specified
           Product: D
           Version: 1.011
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: clugdbug yahoo.com.au


----------
void a(X...)(X expr)
{
    asm {
        mov EAX, expr[0];
    }
}

void main()
{
   a(1);
}
---------

There is a workaround: use
  mov EAX, int ptr expr[0];

Unfortunately, this does not work in the case I want it, when properties
are involved:
(gives an "end of instruction" error).
-----------
void a(X...)(X expr)
{
    asm {
        mov EAX, int ptr expr[0].ptr;
    }
}

void main()
{
    int [] b = [1, 2, 3];
   a(b);
}
-------
There may be a bit more going on here (.ptr may be misrecognised as the asm
'ptr' keyword).

Most of the cases in this report are fixed, but the second one from Don (with
or without the 'int ptr' part now), which contains 'expr[0].ptr' doesn't build
still.  Same error.  That corresponds to the C test case from Thomas.

Closing this issue, created #2455 for the remaining bug (dstress C) which is
really a different bug.
