While we log which IPC message was invalid, we do not know which part of the message caused the decoding failure. This patch introduces a way to log the specific part of a serialized object that failed IPC decoding. This is particularly important for IPC messages that send large objects, such as `WebPageCreationParameters` or `WebProcessCreationParameters`, which contain numerous objects with validators that could potentially cause a crash. 2053210 1 webkit-bug-importer 2024-08-15 21:16:30 -0700 <rdar://problem/134011298> 2053211 2 charliew 2024-08-15 21:19:32 -0700 Pull request: https://github.com/WebKit/WebKit/pull/32285 2053352 3 ews-feeder 2024-08-16 12:08:17 -0700 Committed 282362@main (a56e4d9687cd): <https://commits.webkit.org/282362@main> Reviewed commits have been landed.
