Any particular webpage or webserver triggering this ?

[diver]

Not at the moment. Will try to reproduce.

[pulkomandy]

Assuming fixed as a lot of bugs were fixed in the network code. Reopen if it happens again.

[pulkomandy]

This should be fixed in hrev50917. Can you still reproduce?

[diver]

(In #13263) The original crash in BHttpHeader::NameIs is already being tracked in #10392.

The second crash in WebCore::Region::unite deserves its own ticket as well as the url causing Web+ to hang.

Got this crash with hrev50967. Seems like a null pointer sent to strcmp. I was visiting Amazon, did a search for "ssd" and then clicked on a checkbox on the side to filter the results. I can't reproduce though.

[pulkomandy]

Fixed in HaikuWebKit fe828d4229e, which will be part of the next HaikuWebKit release.
