Hi,
I have a page which uses a lot of synchronized XmlHttpRequests, and
which sometimes crashes JavascriptCore. It is not reproducible in the
sense that it crashes at after the same set/number of GUI actions,
but it is reproducible in that it crashes sooner or later.
Therefore, I don't have any idea of how I can make a simple test case.
The symptoms are always the same. Some function in KJS calls
something in DOM (often attrId) which produces a bus error.
Dumps below are from the code from CVS from a couple of hours ago.
How do I proceed with debugging this problem? It seems like it
crashes when accessing the dom of the xml document returned by
xmlhttprequest, but how do I find out more specific what js it
executes when it crashes?
Safari in 10.4.0 had the problem, and crashed very often.
CVS version and Safari in (latest osx not to be disclosed) crashes
less often, but still.
