memory leaks

Anonymous — Mon, 07 Mar 2011 22:44:46 -0000

when encoding OggFLAC using libFLAC, calling FLAC__stream_encoder_finish() causes memory leaks.
if i don't call this function, no memory leaks occur.

number of those memory leaks depend on whether any metadata are created (don't even have to be added using FLAC__stream_encoder_set_metadata() to cause memory leaks!!!) and whether any samples are encoded (whether FLAC__stream_encoder_process() is called).

i'm using flac-1.2.1

Is this a known issue? I can provide test case, if needed.

example memory leaks:
DEBUG: output from _CrtDumpMemoryLeaks() for LibOggEncoder.dll:
