This is caused by line jrd.cpp/1988:
trace_failed_attach(NULL, filename, options, true, false);
last "false" parameter (from old-style call, before revision 54433) implicitly
converted to NULL status pointer, which is then deferenced in
trace_failed_attach (jrd.cpp, 781):
const bool no_priv = (status[1] == isc_login || status[1] == isc_no_priv);
