#16 segmentation fault

[Ali Kanarya]

I have used your lib before successfully.
After long time, I have an another project now and I am using my own old libnodave related files.
My old working system was QT4. Now I am using QT5 on win8.1.
I am directly loading libnodave.dll in my software.
Compilitation is succesfull but when software comes to make a connection,
at daveNewConnection(..) function call, my software crashes with seg fault error.
opensocketw function works before this call, I am monitoring it.
Plc accepts connection.
I am stuck, any help is highly appreciated.
Thanks. Ali.
