Reduced testcase (why don't we remove the dead code before inlining).
void g(void);
inline int f(void)
{
  return 1;
  g();
}
int h(void)
{
  return f();
}

Note this is reduced from:
#include <string>
#include <vector>
void foo(std::vector<std::string> & matches)
{
 char * buf[10];
 matches.insert(matches.end(), buf, buf + 10);
}

(also why does libstdc++ have dead code in its headers.
