Hello.
I've been playing with following example:
#include
class Base
{
public:
virtual ~Base() {}
};
class Derived: public Base
{
};
#define N 1000
int main()
{
Base **b = (Base **)malloc (sizeof(Base *) * N);
for (unsigned i = 0; i < N; i++)
b[i] = new Derived();
for (unsigned
I noticed the issue with 4.9.1 (in that x86 Linux'es
this_cpu_read_stable() no longer does what the comment preceding
its definition promises), and the example below demonstrates this in
a simplified (but contrived) way. I just now verified that trunk has
the same issue; 4.8.3 still folds redundant

What should I tell a user who wants to create an account?

Sorry for bringing this up again, but this could work:
void foo(int x, int (*s)[x])
{
(*s)[x] = 1;// <- undefined behaviour
}
Such an access beyond the specified length means that either
1. the array is accessed out-of-bounds or
2. was accessed using an incompatible pointer
and a
13 matches
