Here's what I've got...
It is not deferencing a char* per se that is specifically recognized as a
potential alias of any object, but any address referring to a char object. This
includes an array of char objects, as in the following example which will also
break the strict aliasing assumption.
0 char const cp[4] = { arg0, arg1, arg2, arg3 };
1 uint16_t* const sp= (uint16_t*)cp;
2
3 sp[0] = 0x0001;
4 sp[1] = 0x0002;
http://cellperformance.beyond3d.com/articles/2006/06/understanding-strict-aliasing.html
int main(void)
{
unsigned short foo;
char a[2] = {0};
foo = *(unsigned short*)a;
return foo;
}
gcc -O2 -Wall test.c
test.c:5: warning: dereferencing type-punned pointer will break strict-aliasing
rules
