[Lldb-commits] [lldb] r205555 - Avoid crash if symbol returns a null name

[Greg Clayton]

It is possible to get a NULL name. The ConstString class has the following:

    const char *
    AsCString(const char *value_if_empty = NULL) const

Since no value was provided, it will return NULL if empty, so your fix is good.
