create a directory called test in /home
create a file called main.cpp and a Makefile and put the above code into them, make, execute ./main. A window appears with an editbox, type in asd [enter] randomsh** [enter] random****** [enter] until you cannot see the top of the text anymore, then select text in order to scroll up. If it does not already crash here, select ( from top ) from left to right the text and then down, as if you wanted to scroll down.. now it should crash reporting the following
main: ../../include/irrString.h:330: T& irr::core::string<T, TAlloc>::operator[](irr::u32) [with T = wchar_t, TAlloc = irr::core::irrAllocator<wchar_t>]: Assertion `!(index>=used)' failed.
Aborted
Hope it really is a bug and not just something I did wrong (:roll:)
If you guys need anymore info ill be glad to help. Is there any chance of this getting fixed ? Maybe even a hotfix just for now ? What is a possible workaround ? Adding a scrollbar ?
Greetings Teknix
