If I comment out the call to g_timer_add_seconds() it does not crash.
Here is what I do:
int main()
{
CFrame *frame = new CFrame();
result = frame->OpenPort();
if( !result )
return 1;
else
{
g_timer_add_seconds( 1, (GSourceFunc) frame->ReadData(), NULL );
gtk_widget_show( window );
frame->ReadData();
gtk_main();
}
}
in frame.h:
class CFrame
{
void ReadData();
}
Do you see any problems with that?
Basically followed example from http://zetcode.com/tutorials/gtktutorial/gtkevents/.

Just run the program under gdb and get the point of crash.
Check all the variables at runtime under gdb.
Then study the code and see what the problem is.
Thank you.
