audacity crashed with SIGSEGV when pressing Ctrl-Z

[Jim Braux-Zin]

Binary package hint: audacity

I autogenerated markers between each track from a recorded sound file. I then tried to modify those markers and made a mistake. So I hit Ctrl-Z to cancel my last action, then Audacity crashed (luckily it was able to restore my project on the next launch).

I tried to reproduce this bug and it seems that this is the way:
* Record a new track
* Add a markers track
* Do some stuff anywhere (you don't even have to add markers)
* Hit Ctrl-Z

I can reproduce this bug:
* Record a new track (start it and stopped it after some seconds)
* Add a markers track (and give them a name)
* Select a part of the track and use Effect -> Amplify.
* Hit Ctrl-Z twice

The current cvs checkout is not affected any more. This bug will be fixed in the next upstream release (1.3.10).

Fixed in 1.3.9-6
