           Summary: Severe GC leaks with repetitive array allocations
           Product: D
           Version: 1.026
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: webmaster at villagersonline.com


Linux (Fedora 6), 64 bit

The following program will run out of memory when the allocations reach about 8
MB.  The problem happens on *both* 1.026 and 2.010

FYI: I tried running fullCollect() periodically, just in case...no luck.

  import std.stdio;
  void main()
  {
    for(int i=1; ; i++)
    {
      auto tmp = new char[i*1024];
      if(i % 1_000 == 0)
        writefln("%d iterations, roughly %.1f MB", i,
tmp.length/(1024*1024.0));
    }
  }
