1273123 - [Static Analysis][Uninitialized scalar field] In constructor nsPresState

Status: RESOLVED FIXED

(Core :: Layout, defect)

Description

[Andi-Bogdan Postelnicu [:andi]]

The Static Analysis tool Coverity added that variable |mRestoringHistoryScrollPosition| is uninitialized. As we are trying to push for a more RAII architecture and we want to prepare our code for this clang-plugin - 525063. We should initialize these member variables.

Is that a bug number?  If so, I can't access it.

This member variable is unused.  Instead of initializing it, you should remove it.

Yes it is a bug number but it was marked as security issue and that's why you were unable to open it, I've added you to the cc list.
