           Summary: CTFE fails when mutating a struct in an array
           Product: D
           Version: 2.012
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: samukha voliacable.com


Error: cannot evaluate foo() at compile time

struct S
{
    int x;
}

int foo()
{
    S[] a = [];
    a ~= S();

    a[0].x = 1; // Fails 

    return 0;
}

enum x = foo();

Btw, CTFE is relatively difficult to debug. More informative messages than
"cannot evaluate ... at compile time" would be appreciated.

This applies to D1.0 as well.

For D1.0, change last line of test case to:
int x = foo();
