Extended Description
noinline int forever( int x)
{
if( _eq_SxS_( x,0))
res = forever(x);
else
res = 42;
return res;
}
int main() {
return forever( 0);
}
after optimisation yields 42 :-(
What happens is that the type of the function forever is computed as int{42}. The constant folder reacts and throws the conditional away.....
