Summary: [ATK] Leak: title leaks in AccessibilityUIElement
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: Accessibility
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: brian.holt at samsung.com
+++ This bug was initially created as a clone of Bug #118362 +++
When I reported this originally I did so thinking that both bugs could be fixed in the same file fairly easily.
However the leak below in AccessibilityUIElement::title calls webkitAccessibleGetName(AtkObject*) that sometimes returns a char* that is created by g_strdup but it also sometimes returns a value stored in a cache. Freeing that would be a disaster.
This is probably not worth the effort required to refactor to fix the few bytes leaking, but opening this bug to track it anyway.
