[Live-devel] Stack overflow caused by recursive destructors

[Chmelev, Anton]

Hello,

I'm using liveMedia library to develop video recording application.
Turns out, when you try to record a really big file (like, several hours) you get stack overflow.
The problem is that linked lists are destroyed recursively in the code (eg. AVIIndexRecord in AVIFileSink, ChunkDescriptor in QuickTimeFileSink).
Although this issue can be addressed by incrementing stack size, why not use iterated destruction?

  // Then, delete the index records:
  /// delete fIndexRecordsHead;

  AVIIndexRecord *cur = fIndexRecordsHead;

  while (cur)
  {
    AVIIndexRecord *next = cur->next();

    delete cur;
    cur = next;
  }
