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 |
|
