[Tremor] Memory leaks in Tremor code : low branch version (Bharan Giridhar) AW: Tremor Digest, Vol 33, Issue 1

[Lorber, Markus]

Hi Bharan!

Maybe I have told you this before...

My final solution with the Tremor code adaption for the Blackfin DSP was:

1. To do the same patches as you mentioned (but proplems with stack and heap remaind)
2. To replace all alloca()'s by malloc() and free()  -> This solved the stack problems but not the heap problems.
3. To give every OggVorbis channel its own heap. After having finished playback on this channel, additionaly to the ogg_clear() I perform a clearing of the corresponding heap. So The remaining memory leaks do not desturb me any more.  This is possible on the Blackfin DSP as you can define several heaps there.

If you are able to define several heaps on the Sharc, this could propably solve your remainig problems.

Best Regards and good luck,
Markus

Hello

I am implementing the tremor code (low branch version) on the SHARC ADSP
21364. The code works fine, however I found that:

1. The heap continues to grow perennially (though slowly) which I believe is
because of some existing memory leaks. Could you please suggest a list of
all possibilities where this leak could occur?
2. Also, I have already applied the patch for fixing _ogg_buffer_destroy()
and ogg_stream_destroy() leaks.

Please reply asap.

Bharan
