Yes w/o UDF the bug does not happen, the bug happen only with call to UDF which the fbembeded. The same program with others protocols connections works perfectly even with UDF. The UDF is very simple for the test program : char * uuid1maccompr(); char *uuid1maccompr() { return 0; } I don’t know if you have seen in my previous message but if I compile firebird in debug the problem does not happen.
