Hi, Thanks for the report. I can't reproduce here. Can you upload a session which crashes on export? Thanks Carl |

Carl, I have uploaded a simple session that reproduces this crash. Here are details. This session has one track with audio. There is one buss as well. Track 1 includes a prefader insert connected to the buss. Note that I have not included any plugins in this example. If you right click the audio track in the editor window, you can select option 'bounce' which correctly creates a bounce region (in this case a duplicate of the track. Output from ardour is... >Result of bounce of martin right-2 len = 30656512 was martin right-2-0-bounce-1 len = 30656512 Now do the same thing, except make the insert active. This should crash with the following output: >ardour-2.7.1: ../common/JackGraphManager.cpp:44: void Jack::AssertBufferSize(jack_nframes_t): >Assertion `buffer_size <= 8192' failed. Note that I am using the most up to date jack (jackdmp 1.9.1) on a fedora 8 system. Kernel is from CCRMA (2.6.24.7-1.rt21.1.fc8.ccrmart x86_64). Thanks. Hope this helps. -Joe D |

Hi Joe, Thanks for that, confirmed here. I think this may caused by a bug in JACK. The attached patch for ardour works around it, and fixes the problem for me. But it's not a "proper" fix. I'm trying to work out whether ardour or JACK are in the wrong :) Many thanks for your help with this. Carl |
