webkit crash log

I've been maintaining a benchmark library comparing performance of a series of JavaScript libraries for doing matrix operations. Most of these libraries use JavaScript typed arrays which spun out of the WebGL standard,.

You can run the benchmarks here: http://stepheneb.github.com/webgl-matrix-benchmarks/matrix_benchmark.html

Right now when I open this page with WebKit nightly: 85595 it crashes.

These used to work in WebKit nightly ... much more slowly than in Chrome or Minefield, but they worked.

FYI: this is how fast they run on Minefield: https://img.skitch.com/20110504-qbt1ajmg948jay37nasfwhtg2a.jpg

The repository for the source code is: https://github.com/stepheneb/webgl-matrix-benchmarks

There were some recent changes -- I'll see if older versions of the matrix benchmarks worked and if a specific commit is causing the problem for WebKit nightly I'll report back here.
