WebUndefined behavior may also cause buffer overflow attack, if for example an array out of bounds is not checked. The advantage of undefined behavior in C is that the program avoids the unnecessary checking (such as arrays out of bounds), that results into better performance. C99 international standard presents a list of 191 undefined behavior cases. WebBus errors occur when you're trying to access an address which doesn't exist. Check in your code you've assigned pointers correctly, especially uses of the * and & unaries, since * can dereference a pointer variable. It'd be helpful to see your code and the gcc output with the -Warn and -Wextra flags. bananaskywalker • 4 yr. ago
