With debug build on Xubuntu, clean prefs.
To reproduce:

1) Generate a chirp (default settings)
Audacity crashes.

Where is your heat commit?

Is this consistently reproducible?

Is not NOT reproducible BEFORE d3c9a1decb41b5ef27443dd7e9377ffe8363c3b3?

That commit caused it, but perhaps. It changed the timing of the
processing of certain events. They were not paint events, but maybe they
are dispatched after certain paint events rather than before and that
causes it.

That doesn't quite answer my question. I suspect my own commit d3c9a1d.
Revert that in your build and tell me if it is fixed thereby.

Steve, I don't get the crash on Mac, but I reasoned about the code and I
think the fix for it is now at 2806b509e23ff154b67b93be6630ff2fe718896b

Is this consistently reproducible?
Yes, but not only Generate effects. For example, "Amplify" also crashes.
That's good, for investigating it.

Is not NOT reproducible BEFORE d3c9a1decb41b5ef27443dd7e9377ffe8363c3b3?
That commit caused it, but perhaps. It changed the timing of the
processing of certain events. They were not paint events, but maybe they
are dispatched after certain paint events rather than before and that
causes it.
My previous build was on Friday 23rd.
Steve
That doesn't quite answer my question. I suspect my own commit d3c9a1d.
Revert that in your build and tell me if it is fixed thereby.
