           Summary: Segfault using tuple inside asm code.
           Product: D
           Version: 1.007
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: ice-on-valid-code
          Severity: normal

         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: clugdbug yahoo.com.au


Line (1) causes a segfault.
Line (2) causes an ICE.

Dsymbol::toSymbol() 'var1', kind = 'alias'
Assertion failure: '0' on line 103 in file 'tocsym.c'

--------
void a(X...)(X expr)
{
    alias X[0] var1;
    asm {
        fld double ptr X[0];   // (1) segfaults
        fstp double ptr var1;  // (2) ICE
    }
}

void main()
{
   a(3.6);
}

The situation shown in the test case was fixed in DMD 1.011. The ICE seems to
be genuinely fixed, but the segfault still occurs in slightly more complex

Fixed dmd 1.011

But the X[0] must be replaced with expr[0].
