Better backtrace attached.

Maybe it's caused by https://bugs.webkit.org/show_bug.cgi?id=179675, though may backtrace is totally different

Is this a crash or assertion?

Comment 4 2017-11-14 11:16:20 PST
Attached backtrace is from release version where asserts are disabled, and Length::calculationValue() doesn't have RELEASE_ASSERT. So it's not enough to state that these two issues are same

Need to test to see if this still occurs.

I'm pretty sure this is a duplicate of bug 237389, so I'm closing this. We can reopen if we see these kind of crashes again. *** This bug has been marked as a duplicate of bug 237389 ***
