I'm confused your still crashing even with the vt fix ?
Also I did not see the email with the new vt patch you talked about it though :)
>From this email I think the following is happening.
The vt switch patch is probably correct and were no longer crashing in pthreads.
The cleanup or shutdown code is not working correctly when and app
quits when its vt
is not active. It either should switch the vt back to itself before
shutting down or we need to fix that bug also. As far as getting
problem with no vt-switch enabled I don't think that will really work
since directfb must disable itself when the vt is switched. I assume
thats there simply to not start the vtswitch thread.
Getting closer I think.
