[Qemu-devel] Triple-fault causes abort(), which doesn't end pointer grabs

[Qemu-devel] Triple-fault causes abort(), which doesn't end pointer grabs

[Samuel Bronson]

So, if the guest system has a triple-fault, and I had had my mouse grabbed, it
stays grabbed, so that X has to be restarted (as far as I know).

This happens because abort() doesn't run functions registered with atexit().
Suggest use of exit() instead.

Sounds like an X server bug to me.

Not if you have XF86_Ungrab bound to a key.

That's a workaround, not a fix.

Possibly. Certainly it is not a desirable behaviour. But atexit()
handlers are there for a reason...

It might also be an SDL bug. actually.

Sorry I took so long to reply.
