A simple repro case is attached. <rdar://problem/14933505> 933705 1 tony 2013-09-26 14:27:18 -0700 I tried this in a debug build of blink, but blink doesn't hit this assert. This is probably because blink doesn't support MathML. 986309 2 rhodovan.u-szeged 2014-03-03 02:20:02 -0800 (In reply to comment #1) > I tried this in a debug build of blink, but blink doesn't hit this assert. This is probably because blink doesn't support MathML. I can reproduce this issue (or at least the same assertion fail) on the TotT Blink with a different test case. The issue with the test case is reported here: https://code.google.com/p/chromium/issues/detail?id=335121. 1139913 3 264921 rhodovan.u-szeged 2015-11-06 02:03:16 -0800 Created attachment 264921 Repro 2 An even shorter repro is: <math><menclose> 1174390 4 fred.wang 2016-03-14 03:54:45 -0700 I didn't not try the testcase, but I'm making this depends on bug 153991 where MathML will have its own layout, independent from flexbox. 1205514 5 fred.wang 2016-06-27 03:54:09 -0700 I no longer have this assert after the MathML refactoring (probably fixed by bug 155019 and 153918). I'm still waiting bug 153991 before closing this bug so that we are sure that code will never be executed with MathML. 1208815 6 fred.wang 2016-07-07 15:14:07 -0700 Fixed by http://trac.webkit.org/changeset/202934, since MathML no longer execute RenderFlexibleBox code. 211100 2013-09-09 15:12:36 -0700 2013-09-09 15:12:36 -0700 Repro flex-main-axis-assertion.html text/html 175 jeffrey+webkit PCFET0NUWVBFIGh0bWw+PGh0bWw+Cjxib2R5Pgo8cCBzdHlsZT0iLXdlYmtpdC13cml0aW5nLW1v ZGU6IHZlcnRpY2FsLWxyOyI+CjxtYXRoPgo8bXN1YnN1cD4KPG1uIGRpcj0icnRsIj4KPC9tbj4K PG1vIGRpcj0ibHRyIj4KPC9tbz4KPC9tc3Vic3VwPgo8L21hdGg+CjwvcD4KPC9ib2R5Pgo8L2h0 bWw+Cg== 264921 2015-11-06 02:03:16 -0800 2015-11-06 02:03:16 -0800 Repro 2 test.html text/html 305 rhodovan.u-szeged CjwhLS0gc2F2ZWQgZnJvbSB1cmw9KDAxMDIpaHR0cDovL2Z1enplci5hdGVhbS5zZWQuaHUvZnV6 emluYXRvci9URVNUUy9GQUlML3JlbmlmdXp6L2EzMTA3ZTg3NWE4YTRkZWYwZGQwZGI5NTIxMjY0 MWJiXzQvdGVzdC5odG1sIC0tPgo8aHRtbD48aGVhZD48bWV0YSBodHRwLWVxdWl2PSJDb250ZW50 LVR5cGUiIGNvbnRlbnQ9InRleHQvaHRtbDsgY2hhcnNldD1VVEYtOCI+PHN0eWxlIHR5cGU9InRl eHQvY3NzIj48L3N0eWxlPjwvaGVhZD48Ym9keT48bWF0aD48bWVuY2xvc2U+PC9tZW5jbG9zZT48 L21hdGg+PC9ib2R5PjwvaHRtbD4=
