Hi !

I am developping a serial data frame decoder based on the Win_QextSerialPort class that can be found on sourceforge.

It works quite well in debug mode and never crashes but when I launch the release version it crashes, telling me that an instruction uses memory adress 0x00000000 and that memory cannot be written ... in fact it is an access violation

My problem is that it never happens in debug version but always in release version, why ?

Another thing, how could I make to know the line and file where this access violation occurs in release mode ?

Thanks in advance.
