Subject: [PATCH] Another variation of overflow in Conditional sections

To: libvir-list@redhat.com

Which happen after the previous fix to

https://bugzilla.gnome.org/show_bug.cgi?id=756456

But stopping the parser and exiting we didn't pop the intermediary entities

and doing the SKIP there applies on an input which may be too small
