Summary REGRESSION(r187013): cannot open tddbin.com anymore "quit unexpectedly"

Created attachment 257080 [details] Crash Report r187013: "quit unexpectedly - A problem repeatedly occurred with tddbin.com" r187008: works I would suspect https://trac.webkit.org/changeset/187012 being the cause because it's a heavy change. tddbin.com is a "no-install/setup testing environment" from uxebu and it makes use of block scoping, const and let. Another interesting page in that regard is http://tddbin.com/#?kata=es6/language/block-scoping/const. It offers several use cases to test block-scoping.

In fact, my testcase makes r186963 crash, while r186927 works. Either the crash of tddbin.com is unrelated to my testcase, or it was a side-effect of another change in WebKit.

Seems to be fixed in r187018. Can you confirm (and, if yes, close the bug)? I suspect that it was due to Bug 147105.
