Using Debian Sid, fairly up-to-date but full upgrading is a mess right now. Gcc,g++ are most recent. Muse is compiled with VST enabled. Tried with and without processor specific compile and optimizations. That -O3 seems hard wired in the sub-folder Makefiles. Muse 1. Checks for Jack 2. Checks ladspa plugins (complains about some of them lacking a symbol but will still segfault if I run with "-p"). 3. Attempts to reserve a slug of memory. 4. Segfaults.

I could try a dbg run and post the traces. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-user
