Hi Yusuke,
I was able to build the latest JSC using webkit 2.26.1 (250230) and applied the patch (https://trac.webkit.org/changeset/251307/webkit) you mentioned and after running the stress test ~3400 times, we don't see the JSC crash which gives us some confidence to put this version of JSC out in the field and see how it performs against the larger scale and data.

The reason I could not get the stacktrace from all threads is, we are unable to reproduce it reliably but if we run stress tests multiple times, it is likely to report the JSC crash once or twice in 1000 automated runs and getting the stacktrace at this stage would not be possible.

Thanks for all your help and we are keeping eye on this new JSC (250230) version to see if it crashes. I will keep you posted.
