Which C++ library, IBPP?

Most probably a bug in Firebird that made the engine crash. I haven't
used 2.5 much, but I know of some in 2.1 that did this.
You should log your SQL statmenets to capture the one that causes this.
If you use IBPP it's easy to add application-level logging to IBPP's
IStatement class because all SQL is routed through it. For example,
adding this to start of StatementImpl::Prepare() function in
statement.cpp does the job for me most of the time:
--------------------------- statement.cpp ----------
void StatementImpl::Prepare(const std::string& sql)
{
printf("%s\n", sql.c_str());
....
----------------------------------------------------
Since it uses standard C++ you can use simple C++ streams to capture
stuff like parameters as well (take a look at row.cpp file).
