[Issue 2952] New: Segfault on exit when using array ops with arrays of doubles larger than 8 elements
http://d.puremagic.com/issues/show_bug.cgi?id=2952

          Summary: Segfault on exit when using array ops with arrays of
                   doubles larger than 8 elements
          Product: D
          Version: 2.029
         Platform: PC
       OS/Version: Linux
           Status: NEW
         Severity: normal
         Priority: P2
        Component: DMD
       AssignedTo: bugzilla@digitalmars.com
       ReportedBy: lmb@stackedboxes.org


This program causes a segmentation fault when exiting:

void main()
{
  double[9] array;
  array[] *= 2;
}

Curious things:

1. The program seems to actually execute correctly. I mean, adding more code to
the program, including other array operations and printing the contents of
'array' results in the expected behavior -- but it keeps segfaulting on exit.

2. Replacing 'double' with 'float', 'real', 'int' (and possibly others) makes
the program work correctly.

3. Using an array with less than 9 elements makes the program work correctly.

This applies also to Windows, and to D1.

I have fixed this but can't post it to the runtime source since dsource is
down.

In an earlier thread on one of the newsgroups, Sean expressed a preference to
bugzilla based bug reports for druntime.

I've fixed this in SVN for both D1 and D2.
