Summary0005220: Resizing Region Malfunction
Description
resizing an audio region under certain conditions crashes ardour.

how to reproduce:
a) create short audio region
b) drag x-fade handle on top right to top left, creating an x-fade at end of region that starts at start of region
c) resize region from right edge making it smaller ->

JackEngine::XRun: client = ardour was not run: state = 1
JackAudioDriver::ProcessGraphAsyncMaster: Process error


observation: happens as soon as start point of right-side x-fade is 'crossing' start of region when resizing region from right edge to the left

these are undebuggable :(

I can't reproduce this, and it seems likely to me that the bug has been fixed along with the recent fade changes. tom_, can you still trigger this crash?

It's most likely an issue with libart_lgpl and/or the specific gtk version.
both tom_ and me are on 32bit debian/wheezy.

glib-2.32.4 + glibmm-2.32.1 + libart_lgpl-2.3.21

I can not reproduce this on my 64bit machine but reliably on the 32bit one.

The issue was introduce by recent changes to [remove] x-fades and not present around 13572. The issue started coming up early December '12.

it happens with svn 13974 and the 3.0rc1 bundle

as x42 noted, it is likely a system/library specific issue

seem to be gone away with version 3.2.x
