[platform-swt-dev] Intermittent Crash on OS X (CTabFolderRenderer.fillRegion/Callback.bind)

Hi All,

We've recently gotten reports of crashes in the RCP version of our
application, based on Eclipse 3.6.2. The crash happens in both OS X 10.6
and 10.7, but not on Windows or Linux. I've searched for the crash
fragment in bugs but to no avail. We have not been able to reproduce it.
Any suggestions on what might cause such a bug, or if a newer version of
the SWT libs (perhaps from 3.7) might solve this issue?
