Hello to all!
I would like to make a quick question.
G++ seems to allow this:
int& x = x;
which creates a null int reference. Why does G++ allows this? Is it a
standard thing? This doesn't even generates a warning, and such code can
easily cause a segfault.
I am actually getting 2 warnings with g++-5 -Wall:
x.c:2:7: warning: reference 'i' is initialized with itself [-Winit-self]
int&i=i;
^
x.c:2:9: warning: 'i' is used uninitialized in this function
[-Wuninitialized]
int&i=i;
^
