Yes, this code is full of undefined behaviour.  It seems they also ran into
problems when compiling with newer versions of gcc, see:

https://sourceforge.net/p/codeblocks/code/10875/

But this workaround is pretty bad.  They should rewrite the code to use
pointers, not in the least because they seem to abuse references as if they
were pointers. :)
