           Summary: GDC evaluates rvalue of array assignment repeatedly
           Product: GDC
           Version: 0.19
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: glue layer
        AssignedTo: braddr puremagic.com
        ReportedBy: akaquinn hotmail.com


In array assignments of a scalar into an array (ie emulating memset), the
expression is evaluated repeatedly.  It is NOT evaluated repeatedly in DMD.

This error appears to exist in every version of GDC (0.19, latest 0.20 from
SVN, latest trunk from SVN)

Reproduction:

[gregor glapgor test]$ cat test.d
extern (C) int printf(char *, ...);

int main()
{
    int[10] a;
    a[] = printf("Ha-HAH\n");
    return 0;
}

[gregor glapgor test]$ gdc test.d
[gregor glapgor test]$ ./a.out
Ha-HAH
