What version of Jack are you using? I was able to get crashes on preset loading on a freqtweak that was compiled against an earlier version of Jack than what was being run. Since you've recompiled it several times (presumably against the same version of jack) this probably isn't it. I cannot reproduce it when freqtweak 0.4.7 is compiled and run with jack 0.66.3 (gcc 3.2.2). Can you send me (off-list) full backtraces from gdb? Is the segfault always in the same place? jlc Michal Seta wrote on Fri, 04-Apr-2003: > Sorry for polluting with my own replies. I spoke too quickly.
