           Summary: ASSERT_NOT_REACHED() touched in
                    WebCore::BidiResolver<WebCore::InlineIterator,
                    WebCore::BidiRun>::createBidiRunsForLine
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: reni at webkit.org
            Blocks: 116980


Failing test case:

<html>
    <b dir="auto"><u dir="LTR"><a dir="auto">
    <a><input></a>
</html>

This bug is probably related to https://bugs.webkit.org/show_bug.cgi?id=116964, since if we remove the <u> tag then we fail on the other assertion check.

The backtrace:

Program received signal SIGSEGV, Segmentation fault.
