Some tests fail with YARR interpreter since r67790 (https://bugs.webkit.org/show_bug.cgi?id=45787): ecma_2/RegExp/exec-002.js ecma_3/RegExp/octal-001.js ecma_3/RegExp/perlstress-002.js ecma_3/RegExp/regress-103087.js ecma_3/RegExp/regress-165353.js ecma_3/RegExp/regress-169497.js ecma_3/RegExp/regress-191479.js ecma_3/RegExp/regress-216591.js ecma_3/RegExp/regress-24712.js ecma_3/RegExp/regress-85721.js js1_2/regexp/everything.js js1_2/regexp/interval.js js1_2/regexp/regress-9141.js 13 regressions found. These tests terminate by segmentation fault. I don't fully investigate the a problem yet but I think it is caused by the patch of the "Yarr JIT code checks BOL (^) each time through loop when in subexpression" bug. I created a simple testcase too: "a".match(/((a)*)/);
