See if the attached patch helps.

Its a bit of a weird problem. avc1394_transaction_block_close() was added in libavc1394 0.5.3 and needs to be called after avc1394_transaction_block() in order to free allocated memory. There doesnt seems to be any way to determine the version installed via its header files.

I sent a note to the author to see what he says.

Seems to compile properly now.

(In [11819]) remove avc1394_transaction_block_close from fw channel changers.
