Re: [Kaldi-developers] Memory grows when running latgen-faster-mapped

[Daniel P. <dp...@gm...>]

That does sound like a memory leak-- try running it for just a few
utterances with valgrind.   It's possible the memory leak happens only
under certain rare circumstances, so if you don't see it there you may
have to run for a thousand utterances or so and see if valgrind
reports a leak.
