           Summary: static array size limitation is too restrictive
           Product: D
           Version: 1.021
          Platform: PC
        OS/Version: All
            Status: NEW
          Keywords: patch, rejects-valid
          Severity: major
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: thecybershadow@gmail.com


Source:
uint[4096][4096] myBigMap;

Output:
bug.d(1): Error: index 4096 overflow for static array

Remarks:
I do not see the purpose for this 'reasonable' limit (as it is called in the
source code). That range is well inside the 32-bit addressing space, and the
size is not restricted by any stack size or data segment restrictions.

------- Comment #1 from bugzilla@digitalmars.com  2008-11-12 04:41 -------
The linker (optlink) fails with symbols that have more than 16Kb of static data. It isn't an onerous restriction, as the array can be easily new'd instead.
