Bug 135366 – Web process crash causes UI process to die with an assertion failure in Connection::exceptionSourceEventHandler

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit2

[Mark Rowe (bdash)]

I've been hitting the following assertion several times a day:

    // Now send along the message.
    kern_return_t kr = mach_msg(header, MACH_SEND_MSG, header->msgh_size, 0, MACH_PORT_NULL, MACH_MSG_TIMEOUT_NONE, MACH_PORT_NULL);
    if (kr != KERN_SUCCESS) {
        LOG_ERROR("Failed to send message to real exception port. %s (%x)", mach_error_string(kr), kr);
        ASSERT_NOT_REACHED();
    }

It typically happens after the web process hits an assertion failure of some sort. Having the UI process die when a web process dies interferes with development.
