[vdr] Debugging vdr crash in ringbuffer.h

[Seppo Ingalsuo <seppo.ingalsuo@iki.fi>]

Hi,

I earlier described the problems with vdr 1.2.6, dxr3 and
Linux 2.6. The crash happens when skipping with green or yellow
key in recording playback mode. After upgrading to gdb 6.0
debugging works again and I can try to find out more. The call stack is

(gdb) where
#0  0x0807aa19 in cDvbPlayer::Action() (this=0x83d91a0) at
ringbuffer.h:92
#1  0x080a73f8 in cThread::StartThread(cThread*) (Thread=0x83d91ac) at
thread.c:143
#2  0x40044974 in start_thread () from /lib/tls/libpthread.so.0

The problematic line in ringbuffer.h is 

  int Index(void) const { return index; }

I'm quite clueless in debugging C++ so I don't know what's the problem.
The debugger says index is "(cIndexFile *)" which at crash point seems
to point to a struct with fields f, filename, size, last, index,
resumeFile, mutex. Shouldn't it be a normal int instead as the type for
Index() suggests? Does this cause the crash, is variable index messed up
somewhere?

Br,
Seppo
