[Tremor] memory leak

[Park Jin Soo]

Hi,

I found that the result of debug mode is different from that of release mode in VC6.0.
There is no problem in debug mode, but in release mode, program is killed
at _ogg_free(oy); in  ogg_sync_destroy().
I tested with the resent version of tremor from cvs with a patch you have sended.
Do you have this experience in VC6.0?
