[Flac-dev] Bug in FLAC++ Stream::set_metadata()

I've found what looks like a bug in FLAC++ inside the Stream::set_metadata() method. It appears that the contained calls to FLAC__stream_encoder_set_metadata() are being passed arguments that point to local stack data (specifically the 'm' parameter which is a table that points to metadata objects). The code inside FLAC__stream_encoder_set_metadata() does nothing but store the given args ('m' and 'num_blocks'). When Stream::set_metadata() exits, those stack objects go out of scope (or alternatively in the MSVC case, they're explicitly deleted). Later inside the encoder's init() function, those destroyed data members are accessed and causes a fault.
I'm new to the mailing list so if this is a known issue, forgive me.
