I have inherited whole project from previous worker. And I don't really
know how project was developed before.
I get this kind of error using functions which look like this:
Function {name(some_struct *struct_name)}{open return_type void}
{code
Fl::lock();
//do smth
Fl::unlock();
//do smth
Fl::flush();
}
It is strange to me that I have this error on two different OS (Mandriva
2007(KDE 3.x) and VectorLinux 6.0(xfce)) and in different functions. But
functions is similar to what I've written before.
And I have this error in different time interval. My app runs for some time and
than it throws this error.
Any help would be appreciated.
