There are several parts in HashTable.h which uses 0xbbadbeef as a bad
value. 0xbbadbeef is the sign extended version of it. This is no
valid pointer and any usage produces undefined behaviour.

Neat, it's failing to build something that is not even shipped. And there
happens to be a -DNDEBUG missing in the gcc call, which means a Makefile
bug.

This is no good idea as this is a valid userspace pointer on most arches. Use abort(3).

This is no good idea as this is a valid userspace pointer on most arches. Use abort(3). These pointers are used in debug builds, which are aimed at webkit developers. The thing is that the rules for testkjs don't disable debug code, which this pointer is. Adding a include(../../WebKit.pri) in JavaScriptCore/kjs/testkjs.pro should solve the problem. (BTW, if you could give that a try, that would be helpful, except if it's going to take a day) Cheers, Mike -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?
