[Pierre-Olivier Latour]

For some time, there has been 10 crashes in the Leopard build bot in LayoutTests/storage:
http://build.webkit.org/results/trunk-mac-intel-pixel/197/results.html

[Pierre-Olivier Latour]

Here's the backtrace (apparently the same for all crashes):

There's a 11th crash with the same backtrace here:
LayoutTests/fast/js/exceptions-thrown-in-callbacks.html

[Simon Fraser (smfr)]

This looks a bit like one of Greg's:

    static Mutex& stringIdentifierMutex = *new Mutex;
...
    static HashMap<String, int>& stringIdentifierToGUIDMap = *new HashMap<String, int>;

[Greg Bolsinga]

I'll pretty sure this is covered by the latest patch in Bug 21810.

[Simon Fraser (smfr)]

Darin committed that. It's related to bug 22061 and bug 22061. I'm guessing we're seeing the same compiler issue discussed in 21810.

[Greg Bolsinga]

Is this applicable anymore?

[Greg Bolsinga]

I do not see LayoutTests/storage nor LayoutTests/fast/js/exceptions-thrown-in-callbacks.html in today's Mac Leopard skip list, so these tests are now successfully running.

So this can be closed.
