This example is from PR 16111:
#include <stdio.h>
float foo ()
{
unsigned int MASK = 0x80000000;
return (float &) MASK;
}
int main() {
printf ("%f\n", foo());
return 0;
}
'g++ -Wstrict-aliasing' does not generate a warning about breaking
strict-aliasing rules. When '(float&)MASK' is replaced with equivalent '*(float
*)&MASK', 'gcc -Wstrict-aliasing' produces expected warning.
