Let me show that on example from TempSpace::setupFile():
> Firebird::StaticStatusVector status_vector;
.....
> try
> {
.....
> catch (const Firebird::system_error& ex)
> {
> ex.stuffException(status_vector);
At this point status_vector contain pointers to dynamic strings allocated by
system_exception object ex.
> continue;
> }
At this point the exception object is released and all dynamic strings are
freed.
status_vector now is pointing to freed memory.
> Firebird::Arg::Gds status(isc_out_of_temp_space);
> status.append(Firebird::Arg::StatusVector(status_vector.begin()));
> status.raise();
Here newly created exception object is trying to copy strings from
status_vector, but
they were already replaced with some garbage and the engine crash.
