           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:

Script started on Sun 19 Nov 2006 05:36:34 PM PST
[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
Ha-HAH
Ha-HAH
Ha-HAH
Ha-HAH
Ha-HAH
Ha-HAH
Ha-HAH
Ha-HAH
Ha-HAH
[gregor@glapgor test]$ exit
exit
