Audio Plugin causes crash (OSX+Live8)

Well i thought this was my code crashing, but it’s not. I’ve built a clean JuceDemo plugin (not a single character modified), with the latest tip.

The crash occurs when:

  1. add JuceDemoPlugin on track
  2. move the slider
  3. save a project
  4. File->New Live Set
  5. save or don’t save doesn’t matter, once you choose, crash

stack looks like this (no juce code on stack so not very useful)

I can’t figure out what’s wrong, this looks like a Live! bug but i’m not sure, i wanted some confirmation (this happens only with JUCE based plugins).

This OSX 10.5.7, intel, Xcode 3.1.4

Is this the same issue i saw on the forum some time ago ? Was this ever fixed ?
