  1. Selur reporter

    removing '--aq-strength 1.5 ' or '--cu-lossless' from the command line seems to 'fix' the issue -> seems like there is a problem with '--aq-strength' in combination with '--cu-lossless'

  2. Steve Borho

    there was a general bug in --cu-lossless for a short while. --aq-strength was probably just making it easier to reproduce.

    Is this crash still reproducible?
