lo master debug build aborts on OUString NULL check in strtmpl.hxx/newFromStr

[Oliver Brinzing <Oliver.Brinzing@xxxxxx>]

Hi,

with lo master debug build:

OUString x;
OUString test = ((x==NULL) || (x.getLenght()==0) ) ? OUString("a") : OUString("b");

will abort lo:

template <typename IMPL_RTL_STRINGDATA>
void newFromStr                                ( IMPL_RTL_STRINGDATA** ppThis,
                                                 const STRCODE<IMPL_RTL_STRINGDATA>* pCharStr )
{
#if OSL_DEBUG_LEVEL > 0
    //TODO: For now, only abort in non-production debug builds; once all places that rely on the
    // undocumented newFromStr behavior of treating a null pCharStr like an empty string have been
    // found and fixed, drop support for that behavior and turn this into a general assert:
    if (pCharStr == nullptr) {
        std::abort();
    }
#endif
    newFromStr_WithLength(ppThis, pCharStr, pCharStr ? getLength(pCharStr) : 0);
}

how to check if OUString is NULL ?
