Bug ID: 230140
Summary: Use of memcpy with overlapping memory pointers
Product: WebKit
Version: Other
Hardware: Unspecified
OS: Unspecified
Status: NEW
Keywords: InRadar
Severity: Normal
Priority: P2
Component: Media
Assignee: webkit-unassigned at lists.webkit.org
Reporter: jean-yves.avenard at apple.com
Problem introduced in bug 229251; the memory buffer content is shifted to the left; the use of memcpy under these circumstances is fine. But it triggers Asan "AddressSanitizer detected: memcpy-param-overlap"
Should change memcpy to memmove here to keep asan happy.
