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. :) --=20 You are receiving this mail because: You are the assignee for the bug.=
