Here is a slightly simpler version. However I haven't figure out how this happen
yet. Here is what I know so far:

1) It happens with two nested inline within one function.
    Inline bar() once the bug does not trigger.
2) It seems have some thing to do with dead statement call to inline functions.

I am still scratching my head on that inline/uninline business. My guess is that
there is some where we short circuit the inline copy due to dead
statement but some
other part of the code does not agree.

#define __u16 unsigned short
int foo(__u16 n);
static inline __u16 f(__u16 val)
{
        return val;
}

static inline unsigned int bar(__u16 n)
{
       switch (n) {
       case (1 ? 1 : f(1)):
               return 4;
       }
}

int foo(__u16 n)
{
	bar(n);
	bar(n);
	return 0;
}
